G975

2A Low Dropout Regulator with Enable

Features

General Description

Adjustable Output Low to 0.8V

260mV Dropout @ 2A, VO 1.2V

The G975 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 VPP voltage 5V and

output voltage programmable as low as 0.8V. The

G975 features ultra low dropout, ideal for applications

where V_OUTis very close to V_IN. Additionally, the G975

has an enable pin to further reduce power dissipation

while shutdown. The G975 provides excellent regula-

tion over variations in line, load and temperature. The

G975 provides a power OK signal to indicate if the

voltage level of VO reaches 92% of its rating value.
