ABSTRACT:
A voltage supply circuit includes a first holding element with a first end and a second end that supplies a voltage held between the first end and the second end to a load, the second end being connected to a ground, and a second holding element with a first end and a second end, the first end of the second holding element being electrically connected to the first end of the first holding element. The voltage supply circuit also includes a charging circuit that charges the second holding element with a voltage higher than the voltage to be supplied to the load in a first mode, and a potential adjusting circuit that shifts a potential at the second end of the second holding element towards a potential at the first end of the first holding element according to the voltage held by the first holding element or the second holding element in a second mode exclusive with respect to the first mode.
