5V VOLTAGE REGULATOR WITH WATCHDOG TIMER

The TA8006SN is an IC specially designed for microcomputer systems. It incorporates a highly accurate constant-voltage power supply (5±0.1V) and various system reset functions. For system reset, it monitors two voltages-84 and 92 of VREG-and has a watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented.

It also has an overvoltage protection function and a current limiter. Since its standby current is as small as 0.7mA (max.), it can be connected directly to an automotive battery.
