G914X

300mA High PSRR, Low-Noise LDO Regulators

Features

General Description

The G914X is a low supply current, high PSRR low

dropout linear regulator that comes in a space saving

SOT-23-5 package. The supply current at no-load is

55µA. In the shutdown mode, the maximum supply

current is less than 1µA. Operating voltage range of

the G914X is from 2.5V to 5.5V. The over-current pro-

tection limit is set at 500mA typical and 400mA mini-

mum. An over- temperature protection circuit is built-in

in the G914X to prevent thermal overload. These

power saving features make the G914X ideal for use

in the battery-powered applications such as notebook

computers, cellular phones, and PDA’s.
