Abstract

A power supply circuit generates the internal power supply voltage intVCC from a first power supply capable of supplying a first power supply voltage Vand a second power supply capable of supplying a second power supply voltage V, which is lower than the first power supply voltage V. A first transistor TRis provided between the first power supply and an output node, whereas a second transistor TRis provided between the second power supply and the output node. A first supply unit supplies the inverted value of an output voltage of the first power supply or the inverted value of a voltage corresponding to the output voltage of the first power supply, to the gate input of the first transistor TR. A second supply unit supplies the output voltage of the first power supply or the voltage corresponding to the output voltage of the first power supply, to the gate input of the second transistor TR
