ilc7082 5 ?2001 fairchild semiconductor corporation operation the ilc7082 ldo design is based on an advanced circuit configuration for which patent protection has been applied. typically it is very difficult to drive a capacitive output with an amplifier. the output capacitance produces a pole in the feedback path, which upsets the carefully tailored dominant pole of the internal amplifier. traditionally the pole of the output capacitor has been ?eliminated? by reducing the output impedance of the regulator such that the pole of the output capacitor is moved well beyond the gain bandwidth product of the regulator. in practice, this is difficult to do and still maintain high frequency operation. typically the output impedance of the regulator is not simply resistive, such that the reactive output impedance interacts with the reactive impedance of the load resistance and capacitance. in addition, it is necessary to place the dominant pole of the circuit at a sufficiently low frequency such that the gain of the regulator has fallen below unity before any of the complex interactions between the output and the load occur. the ilc7082 does not try to eliminate the output pole, but incorporates it into the stability scheme. the load and output capacitor forms a pole, which rolls off the gain of the regulator below unity. in order to do this the output impedance of the regulator must be high, looking like a current source. the output stage of the regulator becomes a transconductance amplifier, which converts a voltage to a current with a substantial output impedance. the circuit which drives the transconductance amplifier is the error amplifier, which compares the regulator output to the band gap reference and produces an error voltage as the input to the transconductance amplifier. the error amplifier has a dominant pole at low frequency and a ?zero? which cancels out the effects of the pole. the zero allows the regulator to have gain out to the frequency where the output pole continues to reduce the gain to unity. the configuration of the poles and zero are shown in figure 1. instead of powering the critical circuits from the unregulated input voltage, the cmos rf ldo powers the internal circuits such as the bandgap, the error amplifier and most of the transconductance amplifier from the boot strapped regulated output voltage of the regulator. this technique offers extremely high ripple rejection and excellent line transient response. a block diagram of the regulator circuit used in the ilc7082 is shown in figure 2, which shows the input-to-output isolation and the cascaded sequence of amplifiers that implement the pole-zero scheme outlined above. the ilc7082 is designed in a cmos process with some minor additions, which allow the circuit to be used at input voltages up to 13v. the resulting circuit exceeds the fre- quency response of traditional bipolar circuits. the ilc7082 is very tolerant of output load conditions with the inclusion of both short circuit and thermal overload protection. the device has a very low dropout voltage, typically a linear response of 1mv per milliamp of load current, and none of the quasi-saturation characteristics of a bipolar output devices. all the good features of the frequency response and regulation are valid right to the point where the regulator goes out of regulation in a 4 millivolt transition region. because there is no base drive, the regulator is capable of providing high current surges while remaining in regulation. this is shown in the high peak current of 500ma which allows for the ilc7082 to be used in systems that require short burst mode operation. notes: 1: absolute maximum ratings indicate limits which when exceeded may result in damage to the component. electrical specifica- tions do not apply when operating the device outside of its rated operating conditions. 2: specified min/max limits are production tested or guaranteed through correlation based on statistical control methods. mea- surements are taken at constant junction temperature as close to ambient as possible using low duty pulse testing. 3: dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the nomin al value measured with an iv differential. 4: guaranteed by design 5: the device?s shutdown pin includes a 2m ? internal pulldown resistor connected to ground. dominant pole output pole 85 db compensating zero unity gain frequency gain on/off gnd v out v in c noise feedback bandgap reference v refd error amplifier trans- conductance amplifier internal v dd figure 1: ilc7082 rf ldo frequency response figure 2: ilc7082 rf ldo regulator block diagram
ilc7082 6 ?2001 fairchild semiconductor corporation shutdown (on/off) operation the ilc7082 output can be turned off by applying 0.4v or less to the device?s on/off pin (pin 3). in shutdown mode, the ilc7082 draws less than 1ma quiescent current. the output of the ilc7081 is enabled by applying 1.5v to 13v at the on/off pin. in applications were the ilc7082 output will always remain enabled, the on/off pin may be connected to v in (pin 1). the ilc7082?s shutdown circuitry includes hysteresis, as such the device will operate properly even if a slow moving signal is applied to the on/off pin. the device?s shutdown pin includes a 2m ? internal pull down resistor connected to ground. short circuit protection the ilc7082 output can withstand momentary short circuit to ground. moreover, the regulator can deliver very high output peak current due to its 1a instantaneous short circuit current capability. thermal protection the ilc7082 also includes a thermal protection circuit which shuts down the regulator when die temperature exceeds 170c due to overheating. in thermal shutdown, once the die temperature cools to below 160c, the regulator is enabled. if the die temperature is excessive due to high package power dissipation, the regulator?s thermal circuit will continue to pulse the regulator on and off. this is called thermal cycling. excessively high die temperature may occur due to high differential voltage across the regulator or high load current or high ambient temperature or a combination of all three. thermal protection protects the regulator from such fault conditions and is a necessary requirement in today?s designs. in normal operation, the die temperature should be limited to under 150c. adjustable output voltage figure 5 shows how an adjustable output voltage can be easily achieved using ilc7082-adj. the output voltage, v out is given by the following equation: v out = 1.24v x (r1/r2 + 1) for best results, a resistor value of 470k ? or less may be used for r2. the output voltage can be programmed from 2.5v to 12v note that an external capacitor should not be connected to the adjustable feedback pin (pin 4). connecting an external capacitor to pin 4 may cause regulator instabil- ity and lead to oscillations. maximum output current the maximum output current available from the ilc7082 is limited by the maximum package power dissipation as well as the device?s internal current limit. for a given ambient temperature, ta, the maximum package power dissipation is given by: p d(max) = (t j(max) - t a ) / ja where t j(max) = 150c is the maximum junction tempera- ture and qja = 333c/w is the package thermal resistance. for example at a = 85c ambient temperature, the maxi- mum package power dissipation is; p d(max) = 195m ? . the maximum output current can be calculated from the fol- lowing equation: i out(max) < p d(max) / (v in - v out ) for example at v in = 6v, v out = 5v and t a = 85c, the maximum output current is i out(max) < 195ma. at higher output current, the die temperature will rise and cause the thermal protection circuit to be enabled. application hints figure 4 shows the typical application circuit for the ilc7082. ilc7082 v out v in c out sot23-5 c in on off 123 4 5 c noise ilc7082-adj v out v in c out sot23-5 c in r1 r2 on off 123 4 5 v adj fig. 3: application circuit for adjustable output voltage figure 4: basic application circuit for fixed output voltage versions
ilc7082 7 ?2001 fairchild semiconductor corporation input capacitor an input capacitor c in of value 1mf or larger should be con- nected from v in to the main ground plane. this will help to filter supply noise from entering the ldo. the input capaci- tor should be connected as close to the ldo regulator input pin as is practical. using a high-value input capacitor will offer superior line transient response as well as better power supply ripple rejection. a ceramic or tantalum capacitor may be used at the input of the ldo regulator. note that there is a parasitic diode from the ldo regulator output to the input. if the input voltage swings below the reg- ulator?s output voltage by a couple of hundred milivolts then the regulator may be damaged. this condition must be avoided. in many applications a large value input capacitor, c in , will hold v in higher than v out and decay slower than v out when the ldo is powered off. output capacitor selection fairchild strongly recommends the use of low esr (equiva- lent series resistance) ceramic capacitors for c out and c noise the ilc7082 is stable with low esr capacitor (as low as zero ? ). the value of the output capacitor should be 1mf or higher. either ceramic chip or a tantalum capacitor may be used at the output. use of ceramic chip capacitors offer significant advantages over tantalum capacitors. a ceramic capacitor is typically cheaper than a tantalum capacitor, it usually has a smaller footprint, lower height, and lighter weight than a tantalum capacitor. furthermore, unlike tantalum capacitors which are polarized and can be damaged if connected incorrectly, ceramic capacitors are non-polarized. low value ceramic chip capacitors with x5r or x7r dielectric are available in the 100pf to 4.7mf range. beware of using ceramic capaci- tors with y5v dielectric since their esr increases signifi- cantly at cold temperatures. figure 12 shows a list of recommended ceramic capacitors for use at the output of ilc7082. note: if a tantalum output capacitor is used then for stable operation impala recommends a low esr tantalum capacitor with maximum rated esr at or below 0.4w. low esr tanta- lum capacitors, such as the tps series from avx corpora- tion (www.avxcorp.com) or the t495 series from kemet (www.kemet.com) may be used. in applications where a high output surge current can be expected, use a high value but low esr output capacitor for superior load transient response. the ilc7082 is stable with no load. noise bypass capacitor in low noise applications, the self noise of the ilc7082 can be decreased further by connecting a capacitor from the noise bypass pin (pin 4) to ground (pin 2). the noise bypass pin is a high impedance node as such care should be taken in printed circuit board layout to avoid noise pick-up from external sources. moreover, the noise bypass capacitor should have low leakage. noise bypass capacitors with a value as low as 470pf may be used. however, for optimum performance, use a 0.01mf or larger, ceramic chip capacitor. note that the turn on and turn off response of the ilc7082 is inversely proportional to the value of the noise bypass capacitor. for fast turn on and turn off, use a small value noise bypass capacitor. in applica- tions were exceptionally low output noise is not required, consider omitting the noise bypass capacitor altogether. the effects of esr (equivalent series resistance) the esr of a capacitor is a measure of the resistance due to the leads and the internal connections of the component. typically measured in m ? (milli-ohms) it can increase to ohms in some cases. wherever there is a combination of resistance and current, voltages will be present. the control functions of ldos use two voltages in order to maintain the output precisely; v out and v ref . with reference to the block diagram in figure 4, v out is fed back to the error amplifier and is used as the supply voltage for the internal components of the ilc7082. so any change in v out will cause the error amplifier to try to compensate to maintain v out at the set level and noise on v out will be reflected into the supply of each internal components of the ilc7082. so any change in v out will cause the error ampli- fier to try to compensate to maintain v out at the set level and noise on v out will be reflected into the supply of each internal circuit. the reference voltage, v ref , is influenced by the c noise pin. noise into this pin will add to the reference voltage and be fed through the circuit. these factors will not cause a problem if some simple steps are taken. figure 5 shows where these added esr resistances are present in the typical ldo circuit. with this in mind low esr components will offer better per- formance where the ldo may be subjected to large load transients current. esr is less of a problem with c in as the voltage fluctuations at the input will be filtered by the ldo. ilc7082 v in sot-23-5 c in on off 123 4 5 c noise rf ldo tm regulator r* r* r c v out c out i c i out figure 5: esr present in c out and c noise
ilc7082 8 ?2001 fairchild semiconductor corporation however, being aware of these current flows, there is also another potential source of induced voltage noise from the resistance inherent in the pcb trace. figure 6 shows where the additive resistance of the pcb can manifest itself. again these resistances may be very small, but a summation of several currents can develop detectable voltage ripple and will be amplified by the ldo. particularly the accumulation of current flows in the ground plane can develop significant voltages unless care is taken. with a degree of care, the ilc7082 will yield outstanding performance. printed circuit board layout guidelines as was mentioned in the previous section, to take full advan- tage of any high performance ldo regulator requires paying careful attention to grounding and printed circuit board (pcb) layout. figure 7 shows the effects of poor grounding and pcb layout magnified by the esr and pcb resistances and the accumu- lation of current flows. note thatparticularly during high output load current, the ldo regulator?s ground pin and the ground return for c out and c noise are not at the same potential as the system ground. this is due to high frequency impedance caused by pcb?s trace inductance and dc resistance. the current loop between c out , c noise and the ldo regulator?s ground pin will degrade performance of the ldo. figure 8 shows an optimum schematic. in this schematic, high output surge current has little effect on the ground cur- rent and noise bypass current return of the ldo regulator note that the key difference here is that c out and c noise are directly connected to the ldo regulator?s ground pin. the ldo is then separately connected to the main ground plane and returned to a single point system ground. the layout of the ldo and its external components are also based on some simple rules to minimize emi and output voltage ripple. ilc7082 sot-23-5 on off 123 4 5 c noise r pcb esr r pcb v in c in i out c out i 1 esr v out r pcb r pcb figure 6: inherent pcb resistance 54 3 2 1 v out i load gnd5 gnd1 i load c in v in gnd2 gnd +ic out +ic noise +ignd on/off c noise load ilc7082 sot-23-5 gnd3 +ic out +ic noise c out i load +ic out gnd4 i load true gnd (0v) ic out c noise figure 7: effects of poor circuit layout
