Voltage Regulator Driver
Description
Ordering number : EN2769B
Monolithic Linear IC
LA5693D, 5693S, 5693M
Voltage Regulator Driver with Watchdog Timer
Overview
Package Dimensions
The LA5693 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 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 lowsaturation voltage regulator.
• Since the CK input has no edge detector, a high degree of flexibility is allowed in applications.
• Variable detection voltage.
• The watchdog time can be made longer.
