A voltage reducing circuit includes an internal power supply section configured to reduce an external power supply voltage supplied from an external power supply to an internal power supply voltage which is lower than the external power supply voltage based on a reference voltage. A first current control section is configured to control a current flowing through the internal power supply section when the internal power supply voltage is lower than a setting voltage. A second current control section is configured to control the current flowing through the internal power supply section when the internal power supply voltage exceeds the setting voltage.
