AUTOMOTIVE, 105°C OPERATION,
5.5 V INPUT, 150 mA VOLTAGE REGULATOR
Rev.1.1_01
The S-19251 Series, developed by using CMOS process technology, is a positive voltage regulator with a low current
consumption, high ripple-rejection and high-accuracy output voltage. This IC has high ripple-rejection of 75 dB typ., and
operates with low current consumption of 20 μA typ.
Also, a built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit
to limit heat are included. In addition to the conventional package SOT-23-5, the super-small packages HSNT-4(1010)B and
HSNT-4(0808)B are 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.
