LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.0
_00
The S-818 Series is a positive voltage regulator developed by CMOS technology and featured by low dropout
voltage, high output voltage accuracy and low current consumption.
Built-in low on-resistance transistor provides low dropout voltage and large output current. A ceramic capacitor
of 2
μF
or more can be used as an output capacitor. A shutdown circuit ensures long battery life.
The SOT-23-5 miniaturized package and the SOT-89-5 package are recommended for configuring portable
devices and large output current applications, respectively.
