Overview
TA8002S/AS TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8002S,TA8002AS 5V VOLTAGE REGULATOR WITH RESET TIMER The TA8002S is an IC specially designed for automotive microcomputer systems.
It produces an output voltage of 5±0.
5V 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.
The TA8002AS produces an output voltage of 5±0.
25V.
FEATURES l Accurate output l Standby output l Low bias current l Power-on reset timer l Operating temperature range l Wide operating voltage range l Small SIP-7 pin : 5 ± 0.

1 2 3 4 5 SYMBOL DESCRIPTION BIAS OUT VCC GND 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 (OUT Pin) ≥HFE× (VIN−0.
7) / (200+R1) (mA) where R1 is the external resistance attached to Bias Pin (kΩ) .
When VCC rises above 2.
7V, the starting current is absorbed in the internal circuit ; instead, the output current OUT is supplied via VCC.
Connected to the base of an external PNP transistor so that the output voltage is stabilized.
Power supply pin for internal circuit.
The output voltage can also be detected at this pin.
Grounded The output voltage can be adjusted by inserting a resistor between ADJ and GND or between ADJ and VCC.
