Voltage Regulator Driver
with Watchdog Timer
Overview
Package Dimensions
The LA5692 is a single-chip voltage regulator for unit: mm
microcomputer system monitor use that performs the 3001B-DIP8
functions of 5V output voltage control, watchdog timer,
and voltage detector. Since the LA5692 can hold the reset
output, it is especially suited for use in peripheral control

and monitor output applications (example : valves used in
refrigeration equipment, hot water supply system).

* : A PNP transistor is connected to the LA5692D, 5692S externally to provide a low-saturation voltage regulator.
Therefore, ICONT100mA will flow, as starting current, in the VCC range where the output cannot be regulated.
