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 15):
A constant voltage power source circuit, including:\n a reference voltage output circuit that outputs a reference voltage; a first amplifier that amplifies a difference voltage between the reference voltage and a feedback voltage dependent on an output current to output an output; a first comparator that compares the output of the first amplifier with the reference voltage; a first selection circuit that selects and outputs either one of the reference voltage and an output of the first amplifier in response to an output of the first comparator; a second amplifier that is supplied with an output the first selection circuit and a feedback voltage dependent on an output voltage and amplifies a difference voltage therebetween to output a driving voltage; and a first output transistor that is provided with a control electrode that is supplied with the driving voltage, and supplies the output voltage to an output terminal.
