TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7900S,TA7900F
TA7900S/F
5V Voltage
Regulator with Watchdog Timer
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 runn...
