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 14):
The constant voltage power source circuit according to  claim 3 , wherein the current feedback circuit comprises:\n a voltage generation circuit that outputs a voltage provided in such a manner that a voltage that is predetermined times as much as a predetermined reference voltage is added to the feedback voltage dependent on the output voltage; a first selection circuit that selects and outputs either one of an output voltage from the voltage generation circuit and the predetermined reference voltage; a differential amplifier that is supplied with a feedback voltage dependent on the output current and an output of the first selection circuit; a comparator that compares the predetermined reference voltage with an output of the differential amplifier; and a second selection circuit that selects and supplies to the amplifier, either of the predetermined reference voltage and the output of the differential amplifier in response to an output of the comparator.
