CS8151C
5.0 V, 100 mA Low Dropout Linear Regulator with Watchdog, RESET, and Wake Up
The CS8151C is a precision 5.0 V, 100 mA micro−power voltage regulator with very low quiescent current (400 µA typical at 200 µA load). The 5.0 V output is accurate within ±1.0% and supplies 100 mA of load current with a typical dropout voltage of 400 mV. Microprocessor control logic includes Watchdog, Wake Up and RESET. This unique combination of low quiescent current and full microprocessor control makes the CS8151C ideal for use in battery operated, microprocessor controlled equipment.
The CS8151C Wake Up function brings the microprocessor out of Sleep mode. The microprocessor in turn, signals its Wake Up status back to the CS8151C by issuing a Watchdog signal.
