Abstract

PURPOSE: To permit formation of a plurality of constant voltage circuits with a reduced number of component parts by forming a main constant voltage circuit and an auxiliary voltage circuit with a common use of a resistor and zener diode.
CONSTITUTION: A series control type main constant voltage circuit CVC1 is formed with a resistor R for biasing a transistor T1, a zener diode D for making the base voltage on the transistor T1 constant and the transistor T1. Also, another series control type auxiliary constant voltage circuit CVC2 is formed with the resistor R, the zener diode D and a separate transistor T2, the resistor R and zener diode D being in common use. These constant voltage circuits are connected to respective loads C1 and C2. Since only one resistor and one zener diode can be used commonly for each of the constant voltage circuits, it is possible to reduce the number of component parts and simplify the circuit construction.
