"The TA7900S, TA7900F is an IC specially designed for micro-computer 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 5V output voltage drops below 92% 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.

Features:

Accurate output : 5±0.25V
Output voltage adjusting pin attached
Power-on reset timer incorporated
Watchdog timer incorporated
Operating temperature range : from −40 to 85°C
Wide operating voltage range : 40V (max.)
