© ABLIC Inc., 2018
AUTOMOTIVE, 105°C OPERATION,
5.5 V INPUT, 150 mA VOLTAGE REGULATOR
WITH SOFT-START FUNCTION
Rev.1.1_00
The S-19252 Series, developed by using CMOS process technology, is a positive voltage regulator with high-accuracy
output voltage which incorporates the soft-start function. This IC has high ripple-rejection of 80 dB typ. and operates with low
current consumption of 36 μA typ.
The S-19252 Series incorporates the soft-start function to adjust the rising time of output voltage immediately after power-on
or after the ON / OFF pin is set to ON. It also has a built-in overcurrent protection circuit to limit overcurrent of output
transistor.
In addition to the conventional small packages SOT-23-5 and SC-82AB, the super-small package HSNT-4(1010)B is added
to the lineup, which realizes higher-density mounting.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to ABLIC Inc. is indispensable.

A ceramic capacitor can be used. (1.0 μF or more)
The rising time of output voltage immediately after power-on or after the
ON / OFF pin is set to ON is adjustable.
The soft-start time of SOT-23-5 can be switched to tSS0 = 0.1 ms typ. /
tSS1 = 1.0 ms typ. with the SST pin.
The soft-start time of SC-82AB is fixed to tSS0 = 0.1 ms typ.
The soft-start time of HSNT-4(1010)B is fixed to either tSS0 = 0.1 ms typ.
or tSS1 = 1.0 ms typ.
Limits overcurrent of output transistor.
Ensures long battery life.
Discharge shunt function "available" / "unavailable" is selectable.
Pull-down function "available" / "unavailable" is selectable.
Ta = 40°C to +105°C
*1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large.
