1 / 39 page S-19311 Series www.sii-ic.com FOR AUTOMOTIVE 125°C OPERATION HIGH-WITHSTAND VOLTAGE CMOS VOLTAGE REGULATOR WITH RESET FUNCTION © SII Semiconductor Corporation, 2015 Rev.1.0_02 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.
