Abstract:
A voltage generator circuit which generates a voltage supplied to an internal circuit, comprising:a power source terminal supplied with a power source voltage; first, second, and third switching elements each having first and second terminals, the first terminal of each of the switching elements being connected to the power source terminal; a first transistor having a first driving capability and a current path which has first and second ends, the first end being connected to the second terminal of the first switching element; a second transistor having a second driving capability different from the first driving capability and a current path which has first and second ends, the first end being connected to the second terminal of the second switching element; a third transistor having a third driving capability different from the first and second driving capabilities and a current path having first and second ends, the first end being connected to the second terminal of the third switching element; and an output terminal which outputs the voltage supplied to the internal circuit and is connected to the second end of each of the current paths of the first, second, and third transistors.
