2A Low Dropout Regulator

Features

General Description

Fixed Output Voltage 1.8V and 2.5V

The G954 is a high performance positive voltage

regulator designed for use in applications requiring

very low dropout voltage at up to 2 Amps. Since it has

superior dropout characteristics compared with regular

LDOs, it can be used to supply 2.5V on motherboards

or 1.8V on peripheral cards from the power supply

thus allowing the elimination of costly heatsinks. The

G954 provides excellent regulation over variations in

line, load and temperature. It provides over current

and over temperature protection functions.

Connect ADJ to GND for Fixed Output Mode

Adjustable Output Using External Resistors

The G954 is available with 1.8V, 2.5V when ADJ pin

connected to GND and adjustable outputs using ex-

ternal resistors in SOP-8 (FD) package.
