Data Sheet 150mA RF ULDO REGULATOR General Description
The AP2202 is a 150mA ULDO regulator which provides very low noise, ultra low dropout voltage (typically 165mV at 150mA), very low standby current (1A maximum) and excellent power supply ripple rejection (PSRR 75dB at 100Hz) in battery powered applications, such as handsets and PDAs and in noise sensitive applications, such as RF electronics. The AP2202 also features logic compatible enable/ shutdown control inputs, a low power shutdown mode for extended battery life, over current protection, over temperature protection, as well as reversed-battery protection. The AP2202 has adjustable, 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.3V and 4.0V versions. The AP2202 is available in space saving SOT-23-5 and SOT-89-3 packages.

Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 1% (TJ=25oC) or 2% (40oCTJ125oC) below its nominal value measured at 1V differential. Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current.

Figure 21. Typical Application of AP2202 (Note 7)
Note 7: Dropout voltage is 165mV when TA=25oC. In order to obtain a normal output voltage, VOUT+0.165V is the minimum input voltage which will results a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is VOUT+0.5V to 13.2V. For AP2202-2.8 version, its input voltage can be set from 3.3V(VOUT+0.5V) to 13.2V. For that of Adj version, any value from VOUT+0.5V to 13.2V is available. R1 and R2 must be correctly selected when setting the output voltage. For example, if 3.0V output voltage is required, R1 and R2 can be set to 10k and 14k respectively. For Adj version, we recommend 2.3V as minimum output voltage.

BCD Semiconductor Manufacturing Limited
Data Sheet 150mA RF ULDO REGULATOR Application Information
Input Capacitor A 1F minimum capacitor is recommended to be placed between VIN and GND. Output Capacitor It is required to prevent oscillation. 1.0F minimum is recommended when CBYP is unused. 2.2F minimum is recommended when CBYP is 100pF. The output capacitor may be increased to improve transient response. Noise Bypass Capacitor Bypass capacitor is connected to the internal voltage reference. A 100pF capacitor connected from BYP to GND make this reference quiet, resulting in a significant reduction in output noise, but the ESR stable area will be narrowed. The start-up speed of the AP2202 is inversely proportional to the value of reference bypass capacitor. In some cases, if output noise is not a major concern and rapid turn-on is necessary, omit CBYP and leave BYP open. Power Dissipation Thermal shutdown may take place if exceeding the maximum power dissipation in application. Under all possible operating conditions, the junction temperature must be within the range specified under absolute maximum ratings to avoid thermal shutdown. To determine if the power dissipated in the regulator reaches the maximum power dissipation (see figure 16,17), using: TJ = PD*JA + TA PD=(VIN-VOUT)*IOUT+VIN*IGND Where: TJTJ(max), TJ(max) is absolute maximum ratings for the junction temperature; VIN*IGND can be ignored due to its small value. TJ(max) is 150oC, JA is 200oC/W for SOT-23-5 package and 165oC/W for SOT-89-3 package, no heatsink is required since the package alone will dissipate enough heat to satisfy these requirements unless the calculated value for power dissipation exceeds the limit. Example: For 2.8V version packaged in SOT-23-5, IOUT=150mA, TA=50oC, VIN(Max) is: (150oC-50oC)/(0.15A*200oC/W)+2.8V=6.133V Therefore, for good performance, please make sure that input voltage is less than 6.133V without heatsink when TA=50oC.
