Overview
CS8151C CS8151C 5V, 100mA Low Dropout Linear Regulator with Watchdog, RESET, & Wake Up Description The CS8151C is a precision 5V, 100mA micro-power voltage regulator with very low quiescent current (400µA typical at 200µA load).
The 5V output is accurate within ±1% and supplies 100 mA of load current with a typical dropout voltage of 400mV.
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.
The Watchdog logic function monitors an input signal (WDI) from the microprocessor.
The CS8151C responds to the falling edge of the Watchdog signal which it expects at least once during each wake-up period.
When the correct Watchdog signa...
