TA8007AS

5 V Voltage Regulator with Watchdog Timer

The TA8007AS is an IC specially designed for microcomputer

systems. It incorporates a highly accurate constant-voltage power

supply (5±0.25V) and various system reset functions. For system

reset, it monitors the output voltage of VREG×88% and has a

watchdog timer which can self-diagnose the microcomputer

system so that program runaway can be prevented. It also has

other monitor functions for checking the operation of the

microcomputer system.

Since its standby current is as small as 1.2mA (max), it can be

connected directly to an automotive battery.
