S-1317 Series
5.5 V INPUT, 100 mA CMOS VOLTAGE REGULATOR
www.sii-ic.com
WITH 0.35 μA SUPER LOW CURRENT CONSUMPTION
© SII Semiconductor Corporation, 2016
Rev.1.0_00
The S-1317 Series, developed by using the CMOS technology, is a positive voltage regulator IC, which features super low
current consumption and low dropout voltage. This IC has low current consumption of 0.35 μA typ. and high-accuracy output
voltage of ±1.0%. It is most suitable for use in portable equipment and battery-powered devices.
