TA8042F

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.
