Global Mixed-mode Technology

2A Low Dropout Regulator with Enable

Features

General Description

Adjustable Output Low to 0.8V

The G966 is a high performance positive voltage

Input Voltage as Low as 1.4V and VPP 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 G966 features ultra low dropout,

ideal for applications where V_OUTis very close to V_IN.

Additionally, the G966 has an enable pin to further

reduce power dissipation while shutdown. The G966

provides excellent regulation over variations in line,

load and temperature. The G966 provides a power OK

signal to indicate if the voltage level of VO reaches

92% of its rating value.
