5.0 V, 100 mA Low Dropout

Linear Regulator with

Watchdog, RESET,

and Wake Up

http://onsemi.com

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.

The Watchdog logic function monitors an input signal (WDI) from

the microprocessor. The CS8151 responds to the falling edge of the

Watchdog signal which it expects at least once during each wake−up

period. When the correct Watchdog signal is received, a falling edge is

issued on the wake−up signal line.

voltage as low as 1.0 V. A RESET signal is issued in any of three

situations. During power up the RESET is held low until the output

voltage is in regulation. During operation if the output voltage shifts

below the regulation limits, the RESET toggles low and remains low

until proper output voltage regulation is restored. And finally, a

RESET signal is issued if the regulator does not receive a Watchdog

signal within the Wake Up period.

ORDERING INFORMATION

See detailed ordering and shipping information in the package

dimensions section on page 11 of this data sheet.

The RESET pulse width, Wake Up signal frequency, and Wake Up

delay time are all set by one external capacitor C

Delay

The regulator is protected against short circuit, over voltage, and

thermal runaway conditions. The device can withstand 74 V peak

transients, making it suitable for use in automotive environments.
