LOW DROPOUT CMOS VOLTAGE REGULATOR

S-814 Series

Seiko Instruments Inc.

1

The S-814 Series is a low dropout voltage, high output

voltage accuracy and low current consumption positive

voltage regulator developed utilizing CMOS technology.

Built-in low ON-resistance transistors provide low dropout

voltage and large output current. A shutdown circuit ensures

long battery life.

Various types of output capacitors can be used in the S-814

Series compared with the past CMOS voltage regulators.

(i.e., Small ceramic capacitors can also be used in the S-814

Series.)

The SOT-23-5 miniaturized package and the SOT-89-5

packages are recommended to use for configuring portable

devices and large output current applications, respectively.

• Lead-free products

*1. Attention should be paid to the power dissipation of the package when the output current is large.

Applications

• Power source for battery-powered devices, personal communication devices, and home electric/electronic

appliances.
