SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.0
_00
The S-1711 Series is a 2-channel positive voltage regulator with a low dropout voltage, high output voltage accuracy, and
low current consumption (150 mA output current) developed based on CMOS technology.
A 1.0
μF
small ceramic capacitor can be used, and a 2-circuit voltage regulator with
±1.0%
high-accuracy output voltage is
incorporated in an SOT-23-6 or super-small SNT-6A package. The A/ B/ E/ F types are 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 the super-small SNT-6A package and a small ceramic capacitor. Also, the low current consumption
makes the S-1711 Series ideal for mobile devices.
Features
1.5 V to 5.5 V, selectable in 0.1 V steps.
