CS8271 Datasheet | Cherry Semiconductor Corporation

Description The CS8271 is an adjustable micropower voltage regulator with very low quiescent current (60µA typical at 100µA load). The output supplies 100m A of load current with a maximum dropout voltage of only 600m V. Control logic includes ENABLE . The bination of low quiescent current, outstanding regulator performance and control logic makes the CS8271 ideal for any battery operated equipment. The logic level patible ENABLE pin allows the user to put the regulator into a shutdown mode where it draws only 50µA of quiescent current. The regulator is protected against reverse battery, short circuit, over voltage, and over temperature conditions. The device can withstand 60V load dump transients making it suitable for use in automotive environments. The CS8271 is pin patible with the National Semiconductor LM2931.
