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 micropower voltage
regulator with very low quiescent current (400 A typical at 200 A
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 wakeup
period. When the correct Watchdog signal is received, a falling edge is
issued on the wakeup signal line.
RESET is independent of V
IN
and operates correctly to an output
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.
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.
