CS8151
5.0 V, 100 mA Low Dropout Linear Regulator with Watchdog, RESET, and Wake Up
The CS8151 is a precision 5.0 V, 100 mA micro−power voltage regulator with very low quiescent current (400 mA typical at 200 mA load). The 5.0 V output is accurate within ±2% 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 CS8151 ideal for use in battery operated, microprocessor controlled equipment.
The CS8151 Wake Up function brings the microprocessor out of Sleep mode. The microprocessor in turn, signals its Wake Up status back to the CS8151 by issuing a Watchdog signal.
