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 typ-
ical 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
unique combination of low quiescent
current and full microprocessor con-
trol makes the CS8151C ideal for use in
battery operated, microprocessor con-
trolled equipment.
. This
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 micro-
processor. The CS8151C responds to
the falling edge of the Watchdog signal
which it expects at least once during
each wake-up period. When the cor-
rect Watchdog signal is received, a
falling edge is issued on the wake-up
signal line.
