TA8045BF Datasheet 5V VOLTAGE REGULATOR WITH WATCHDOG TIMER

Manufacturer: Toshiba

Overview: TA8045BF TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHI TA8045BF 5V Voltage Regulator With Watchdog Timer This IC is designed especially for microcomputer system in automobiles and is capable of providing output voltage 5 ±0.15V without any adjustment. This IC incorporates the system reset function, that is, low voltage reset and watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented. This IC also has an over-voltage protection, current limiter and thermal protection to protect the IC from destruction caused of overstress and load accident. In addition, this IC has a low standby current function, so it can be connected directly to an automotive battery. Weight: 0.14 g (typ.
