CS8321
Micropower 5V, 150mA Low Dropout
Linear Regulator
Description
Features
The CS8321 is a precision 5V
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.
This combination of low quiescent
current and outstanding regulator
performance makes the CS8321
ideal for any battery operated
equipment.
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.
