Global Mixed-mode Technology

Peak 3A, Low Dropout Regulator with Enable

Features

General Description

Adjustable Output Low to 0.8V

Input Voltage as Low as 1.4V and VPP Voltage

The G966A is a high performance positive voltage

regulator designed for use in applications requiring

very low Input voltage and very low dropout voltage at

up to 2 amps. It operates with a V_INas low as 1.4V and

VPP voltage 5V with output voltage programmable as

low as 0.8V. The G966A features ultra low dropout,

ideal for applications where V_OUTis very close to V_IN.

Additionally, the G966A has an enable pin to further

reduce power dissipation while shutdown. The G966A

provides excellent regulation over variations in line,

load and temperature. The G966A provides a power

OK signal to indicate if the voltage level of VO reaches

92% of its rating value.
