Abstract

According to an embodiment, a constant voltage power source circuit has a voltage feedback circuit that controls an output voltage depending on a control voltage. It has a current feedback circuit that detects an output current, keeps the control voltage at a constant voltage until the output current reaches a predetermined current value, and changes a value of the control voltage at a time when the output current reaches the predetermined current value.
