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.

back to the CS8151 by issuing a Watchdog signal.
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.
