application information L5300GJ 14/26 doc id 15480 rev 7 3 application information 3.1 voltage regulator the voltage regulator uses a p-channel mos transistor as a regulating element. with this structure a very low dropout voltage at current up to 300 ma is obtained. the output voltage is regulated up to input supply voltage of 40 v. the high-precision of the output voltage (2%) is obtained with a pre-trimmed reference voltage. the voltage regulator automatically adapts its own quiescent current to the output current level. in light load conditions the quiescent current goes down to 55 a only (low consumption mode). this procedure features a certain hysteresis on the output current (see figure 8 ). short-circuit protection to gnd and a thermal shutdown are provided. figure 23. application schematic the input capacitor c 1 100 f is necessary as backup supply for negative pulses which may occur on the line. the second input capacitor c 2 220 nf is needed when the c 1 is too distant from the v s pin and it compensates smooth line disturbances. the c 0 ceramic capacitor, connected to the output pin, is for bypassing to gnd the high-frequency noise and it guarantees stability even during sudden line and load variations. suggested value is c 0 =220nf ? with esr 100 m . stability region is reported in figure 24 . 9 %$77 /*- 567 9fu (:r (:l 9v *1' (q 9r &  &  5 5 5 (: 5 (: ("1($'5

application information L5300GJ 16/26 doc id 15480 rev 7 3.2 reset the reset circuit monitors the output voltage v o . if the output voltage becomes lower than v o_th then r es goes low with a delay time (t rr ). when the output voltage becomes higher than v o_th then r es goes high with a delay time t rd . this delay is obtained by 32 periods of oscillator. the oscillator period is given by: equation 1 t osc = [(v rhth - v rlth ) x c tr ] / i cr + [(v rhth - v rlth ) x c tr ] / i dr where: i cr = 20 a is an internally generated charge current, i dr = 20 a is an internally generated discharge current, v rhth = 2.5 v (typ) and v rlth = 0.95 v (typ) are two voltage thresholds, c tr is an external capacitor to be put between v cr pin and gnd. reset pulse delay t rd is given by: equation 2 t rd = 32 x t osc figure 26. reset time diagram 3.3 early warning this circuit compares the ew i input signal with the internal voltage reference (typically 2.5 v). the use of an external voltage divider makes the comparator very flexible in the application. this function can be used to supervise the supply input voltage either before or after the protection diode and to give additional information to the microprocessor such as low voltage warnings. v o v cr r es < t rr t rr t osc t rd = 32 tosc v out_th v rhth v rlth
