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*
