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.

Claim (Index 8):
The constant voltage power source circuit according to  claim 4 , wherein the current feedback circuit comprises:\n a differential amplifier that is supplied with a feedback voltage dependent on the output current and a predetermined reference voltage and amplifies a difference voltage therebetween to output an output; a comparator that compares the predetermined reference voltage with the output of the differential amplifier; and a selection circuit that selects and supplies to the amplifier, either one of the predetermined reference voltage and the output of the differential amplifier in response to an output of the comparator.
