L5150GJ application information doc id 15540 rev. 12 15/29 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 150 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 24. application schematic the input capacitor f is necessary as backup supply for negative pulses which may occur on the line. the second input capacitor 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 nf ? with . stability region is reported in figure 25 . &r 9 %$77 /*- 567 9fu 567b$'- (:r (:l 9v *1' (q 9r & & 5 5 5 (: 5 (: *$3*36 c 1 100 = esr 100

L5150GJ application information doc id 15540 rev. 12 17/29 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 = 0.9 v (typ) are two voltage thresholds, c tr is an external capacitor put between v cr pin and gnd.
application information L5150GJ 18/29 doc id 15540 rev. 12 reset pulse delay t rd is given by: equation 2 t rd = 32 x t osc the output voltage reset threshold can be adjusted via an external voltage divider r 1 + r 2 (r 1 connected between r es_adj and v 0 , r 2 connected between r es_adj and gnd) according to the following formula: equation 3 v thre = [(r 1 + r 2 ) / r 2 ] * v res_adj the output voltage reset threshold can be decreased down to 3.5 v. if it is needed to maintain it to its default value (8% below v o_ref typical), it is enough to connect the r es_adj pin directly to gnd. figure 27. reset time diagram 9 r 9 fu 5 hv w uu w uu 7 26& w ug 7 26& 9 rxwbwk 9 5kwk 9 5owk *$3*36
