Abstract
PURPOSE: To obtain a plurality of constant voltage outputs different in the voltage value by means of a series of power supply circuit, by providing a plurality of reference voltage generating circuits to one constant voltage control transistor and suitably changing the reference voltage from the selection.
CONSTITUTION: A plurality of Zener diodes ZDAWZDC are connected between the base of the voltage control transistor (TR)1 of the variable constant voltage control circuit 2 and ground, and TR2WTR4 are provided so that the respective Zener diodes ZDAWZDB can be grounded with the control signal. Further, TR2WTR4 are suitably ON or OFF with the voltage selection signals TAWTC from control the circuit CU, allowing to change the reference voltage and the constant voltae output.
