Voltage output circuit
 Disclosed is a circuit including an NPN transistor of which the collector is connected to a voltage output portion, the emitter is connected to a reference voltage portion, and the base is connected to the voltage output portion through a resistor providing a voltage drop across the base and the voltage output portion, circuit further comprises a pinch resistor connected in parallel to the former-recited resistor to make a reference output voltage Vref of the circuit have a predetermined reference value regardless of a current amplification factor .beta. of the output transistor.
