TA8000S

TA8000S/F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8000S,TA8000F 5V VOLTAGE REGULATOR WITH WATCHDOG TIMER The TA8000S TA8000F is an IC specially designed for automotive microcomputer systems. It produces an output voltage of 5 ± 0.25V without need for adjustment from its accurate reference voltage and amplifier circuit. At power-on, it outputs a reset signal to reset the system. It will also output a reset signal when the 5 V output voltage drops below 85% because of external disturbance or other problem. It also incorporates a watchdog timer for self-diagnosing the system. When the system malfunctions, the IC generates reset pulses intermittently to prevent the system from running away.
