An information processing apparatus includes a first circuit configured to operate by receiving a first voltage or a second voltage higher than the first voltage; a second circuit configured to output a signal indicating which of the first voltage or the second voltage is to be input to the first circuit; and a control unit configured to receive the signal output by the second circuit and to output, to the first circuit, a signal indicating a voltage to be supplied to the first circuit. The control unit is configured to output a signal indicating the second voltage for a period until when the signal output by the second circuit has stabilized, and to output a signal indicating a voltage as indicated by the signal received from the second circuit, after the signal output by the second circuit has stabilized.
