Abstract

PURPOSE:To obtain plural output voltages from a stabilized power supply circuit, bu switching the voltage division ratio of a voltage dividing circuit obtained by a resistance dividing method or the voltage value of a reference power supply. CONSTITUTION:An external signal is applied only to an input terminal 8a, and a relay 7a is actuated with a contact closed. Thus the voltage divided by resistances 1, 2 and 2a is compared with the voltage of a reference power supply 3 through an error amplifier 4 to obtain the 1st output voltage. At the same time, the external signal is applied only to an input terminal 8b to actuate a relay 7b with the contact closed. Thus the voltage divided by resistances 1, 2 and 2b is compared with the voltage of the power supply 3 to obtain the 2nd output voltage. When no external signal exists, the 3rd output voltage is directly obtained.
