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 A 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.
