TA8005S/F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8005S,TA8005F
5V VOLTAGE REGULATOR WITH WATCHDOG TIMER
The TA8005S TA8005F is an IC specially designed for
micro-computer 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×85% and has a watchdog timer which can self-diagnose
the microcomputer system so that program runaway can be
prevented.
Since its bias current is as small as 1.4mA (max.) , it can be
connected directly to an automotive battery.
