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 19):
A constant voltage power source circuit, including:\n a reference voltage output circuit that outputs a reference voltage; a voltage generation circuit that outputs a voltage provided in such a manner that a voltage that is predetermined times as much as the reference voltage is added to a feedback voltage dependent on an output voltage; a first selection circuit that selects and outputs either one of the reference voltage and an output of the voltage generation circuit; a first amplifier that amplifies a difference voltage between an output of the first selection circuit and a feedback voltage dependent on an output current to output an output; a second selection circuit that selects and outputs either one of the reference voltage and the output of the first amplification circuit; a second amplification circuit that is supplied with an output of the second selection circuit and a feedback voltage dependent on the output voltage and amplifies a difference voltage therebetween to output a driving voltage; and an output transistor that is provided with a control electrode that is supplied with the driving signal, and supplies the output voltage to an output terminal.
