CS8321

Micropower 5.0 V,

150 mA Low Dropout

Linear Regulator

The CS8321 is a precision 5.0 V micropower voltage regulator with

very low quiescent current (140

mA typ at 1.0 mA load). The 5.0 V

output is accurate within

±2% and supplies 150 mA of load current

with a typical dropout voltage of only 300 mV.

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 withstand 45 V load dump transients

making it suitable for use in automotive environments.

Features

• 5.0 V ± 2% Output

• Low 140 mA (typ) Quiescent Current

• 150 mA Output Current Capability

• Fault Protection

♦ −15 V Reverse Voltage Output Current Limit

• Low Reverse Current (Output to Input)

• Pb−Free Packages are Available*
