<P>PROBLEM TO BE SOLVED: To provide a multi-output constant voltage power supply in which a second constant voltage power supply outputting a voltage higher than that of a first constant voltage power supply is turned on after the first constant voltage power supply is turned on through a simple arrangement. <P>SOLUTION: The multi-output constant voltage power supply 1 comprising a first constant voltage power supply 11 outputting a first voltage, and a second constant voltage power supply 12 outputting a second voltage higher than the first voltage when an on voltage higher than the first voltage is applied to its control terminal is further provided with a three terminal circuit 14 having a first terminal connected with the output of the first constant voltage power supply 11, a second terminal connected with the control terminal of the second constant voltage power supply 12, and a third terminal connected with a potential V4 higher than the on voltage and arranged such that the voltage at the second terminal becomes higher than the on voltage when the first voltage is outputted. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
