CS8321
Micropower 5.0 V,
150 mA Low Dropout
Linear Regulator
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.
regulator performance makes the CS8321 ideal for any battery
operated equipment.
