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.

Unit (resistance : , capacitance : F)
Note on application
1. For stable operation, place Cin, CO, and TR1 as near to the IC as possible.
2. When used in 0°C or below it, a capacitor of which impedance at high-frequency operation is low and has a good
temperature characteristic (such as SANYO OS-CON capacitor or others) should be used to prevent oscillation.
3. Set VS to the output voltage level where the circuit will be reset using external resistors R1 and R2. VS should be set
to 4V or greater due to internal circuit operation.
4. CCK must be inserted to cut the high range element of clock noise to prevent it from becoming a reset output noise.
5. For Ct, a capacitor which less varies the capacitance according to the temperature should be used.
