CS8221
Micropower 5V, 100mA
Low Dropout Linear Regulator
Description
Features
The CS8221 is a precision 5V,
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.
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.
