G977

Global Mixed-mode Technology

7A Low Dropout Regulator with Enable

Features

General Description

Adjustable Output Low to 0.8V

The G977 is a high performance positive voltage

Input Voltage as Low as 1V and VPP Voltage 5V

140mV Dropout @ 7A, VO 1.05V

Over Current and Over Temperature Protection

Enable Pin

Low Reverse Leakage (Output to Input )

Power SOP-8 (FD) Packages with Thermal Pad

±1.5% Output Voltage

regulator designed for use in applications requiring

very low Input voltage and very low dropout voltage at

up to 7 amps. It operates with VPP voltage 5V and

output voltage programmable as low as 0.8V. The

G977 features ultra low dropout, ideal for applications

where V_OUTis very close to V_IN. Additionally, the G977

has an enable pin to further reduce power dissipation

while shutdown. The G977 provides excellent regula-

tion over variations in line, load and temperature. The

G977 provides a power OK signal to indicate if the

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

VO Power OK Signal

VO Pull Low Resistance when Disable

VO Soft Start when Enable

Applications

The G977 is available in the power SOP-8 (FD) pack-

age. It is adjustable using external resistors.
