G9612

Low-Dropout, 500mA Linear Regulator with Reset

Features

General Description

500mA Output Current, with Foldback Current

The G9612 are low-dropout, linear regulator with

reset function supply 3.4V, 3.3V or 2.5V output for

currents up to 500mA. They are available in a 1.0W

SOT 89-5L package with 0.18 inch²copper heat

sink. Typical dropouts are 560mV at 5V and 500mA.

Other features include foldback current limiting and

thermal overload protection.

Thermal Overload Protection

SOT89-5 Package

The reset function in G9612 detect V_CClevel with

hysteresis, keeping it asserted for time delay de-

termined by external capacitor. The reset output is

active low open-drain output. The detection thresh-

old are 3.9V or 4.2V.

Applications

The output is preset at 3.4V for the G9612A, 3.3V

for the G9612B/C, and 2.5V for G9612D. The reset

threshold is preset at 4.2V for G9612 A/B/D and

3.9V for G9612C.
