CS8221

Micropower 5V, 100mA

Low Dropout Linear Regulator

Description

Features

The CS8221 is a precision 5V,

The regulator is protected against

reverse battery, short circuit, over

voltage, and over temperature con-

ditions. The device can withstand

74V load dump transients making it

suitable for use in automotive envi-

ronments.

■ Low Quiescent Current

100mA micropower voltage regula-

tor with very low quiescent current

(60µA typical at 100µA load). The

5V output is accurate within ±2%

and supplies 100mA of load current

with a maximum dropout voltage

of only 600mV.
