FOR AUTOMOTIVE 125°C OPERATION HIGH-WITHSTAND VOLTAGE

CMOS VOLTAGE REGULATOR WITH RESET FUNCTION

© SII Semiconductor Corporation, 2015

1

The S-19311 Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator with the

reset function, which has high-withstand voltage and high-accuracy output voltage. This IC has a built-in low on-resistance

output transistor which provides a small dropout voltage and a large output current. 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.

High heat radiation TO-252-5S(A) and HSOP-8A packages enable high-density mounting.

Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in

the purpose, contact to SII Semiconductor Corporation is indispensable.
