5V VOLTAGE
REGULATOR WITH RESET TIMER
The TA8001S is an IC specially designed for automotive microcomputer systems. It produces an output voltage of 5 ± 0.5 V 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. Since it is also designed to have a small bias current, power consumption on the system can be reduced.

Power supply starting pin. The starting current is supplied through a resistor to which the input voltage is applied. The output current from this starting current is as follows :
IOUT (VCC Pin) ≥3000× (VIN−0.6) / (200+R1) (mA) where R1 is the external resistance attached to Bias Pin (kΩ) . When the output voltage rises above 2.7V, its control is transferred from the starting circuit to the internal control circuit.
