SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1711 Series
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.
A ceramic capacitor of 1.0

or more can be used for the output capacitor.
