5V, 750mA Low Dropout Linear

Regulator with Lower RESET Threshold

Description

Features

■ 5V +/- 3% Regulated

The CS8129 is a precision 5V linear reg-

ulator capable of sourcing 750mA.

to improve noise immunity. A latching

discharge circuit is used to discharge

the delay capacitor when it is triggered

by a brief fault condition.

The

threshold voltage has been

lowered to 4.2V so that the regulator

can be used with 4V microprocessors.

The regulator is protected against a

variety of fault conditions: i.e. reverse

battery, overvoltage, short circuit and

thermal runaway conditions. The regu-

lator is protected against voltage tran-

sients ranging from -50V to +40V. Short
