Output pin 3
Output current detection pin. By inserting
resistor Rf between this pin and GND, the
output current is detected as voltage. The
output current is limited to a current value set
by VRF/Rf (current limit operation).
Power supply pin providing output.
GND for other than output.
The minimum potential of output transistor is
the RF pin voltage.
Forward/reverse control pin.
