SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.1

The S-1711 Series is a 2-channel positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and
low current consumption (150 mA output current) developed based on CMOS technology.
A 1.0
F
small ceramic capacitor can be used, and a 2-circuit voltage regulator with
1.0%
high-accuracy output voltage is
incorporated in SOT-23-6 or super-small SNT-6A package. A/ B/ E/ F type is provided with a discharge shunt function
allowing high-speed output response when the ON/OFF pin is used.
Compared with the conventional 150 mA output current 2-channel CMOS voltage regulators, high-density mounting is
realized by using super-small SNT-6A package and a small ceramic capacitor. Also, the low current consumption makes
the S-1711 Series ideal for mobile devices.
