CS8321

Micropower 5V, 150mA Low Dropout

Linear Regulator

Features

Description

The CS8321 is a precision 5V

performance makes the CS8321

ideal for any battery operated

equipment.

■ 5V ±2% Output

micropower voltage regulator with

very low quiescent current (140µA

typ at 1mA load). The 5V output is

accurate within ±2% and supplies

150mA of load current with a typi-

cal dropout voltage of only 300mV.

■ Low 140µA (typ)

The regulator is protected against

reverse battery and short circuit

conditions. The device can with-

stand 45V load dump transients

making it suitable for use in auto-

motive environments.
