FOR AUTOMOTIVE 125°C OPERATION HIGH-WITHSTAND VOLTAGE
CMOS VOLTAGE REGULATOR WITH RESET FUNCTION
© SII Semiconductor Corporation, 2015-2017
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.
