2A Low Dropout Regulator with Enable

Features

General Description

Adjustable Output from 1.2V to 4.8V Using Ex-

The G962 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 to regular

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

or 1.5V, 1.8V on peripheral cards from the 3.3V supply

thus allowing the elimination of costly heatsinks. An

enable pin further reduces power dissipation while

shut down. The G962 provides excellent regulation

over variations in line, load and temperature.
