TA8042F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8042F
5V VOLTAGE REGULATOR WITH WATCHDOG TIMER
The TA8042F is an IC specially designed for microcomputer
systems. It features an accurate reference voltage of 5 ± 0.15V
and various system reset functions. The system reset includes a
voltage monitor capable of switching between 4.6V and 4.2V and
a watchdog timer for self-diagnosing the system, to prevent a
system runaway. The protective functions include a reverse
battery polarity, current limiter, and overheat protection. The low
standby current of 1.2mA (max.) enables direct connection to a
car battery.

EXAMPLE OF APPLICATION CIRCUIT
*: Cautions for Wiring:
C1 and C2 are for absorbing disturbances, noise, etc. C3 is for phase compensation.
Connect each condenser as close to the IC as possible.
*: To use Fin, short it to GND.
