CS8221
Description
The CS8221 is a precision 5V,
100mA micropower voltage regulator 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 conditions. The device can withstand
74V load dump transients making it
suitable for use in automotive environments.
