ABSTRACT:
A regulator circuit includes an output circuit outputting an output voltage based on a control voltage, a reference voltage generating circuit generating a reference voltage, an output voltage control circuit comparing the reference voltage with a voltage depending on the output voltage and producing the control voltage based on a comparison result, and a power supply circuit which supplies the reference voltage generating circuit and the output voltage control circuit with a first power supply voltage which is different from a second power supply voltage supplied to the output circuit.
