Voltage Regulator Driver
with Watchdog Timer
Overview
The LA5693 is a single-chip voltage regulator for
microcomputer system monitor use that performs the
functions of 5V output voltage control, watchdog timer,
and voltage detector. Since the LA5693 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).

• An external PNP transistor can be used to provide a low-
saturation voltage regulator.
• Since the CK input has no edge detector, a high degree of
flexibility is allowed in applications.

* : A PNP transistor is connected to the LA5693D, 5693S externally to provide a low-saturation voltage regulator.
Therefore, ICONT≈100mA will flow, as starting current, in the VCC range where the output cannot be regulated.
