Abstract
An apparatus which has a load that consumes a predetermined amount of electric power per unit time includes a power source circuit configured to generate a voltage for driving the load, a capacitor which is connected to a supply line for supplying electric power to the load from the power source circuit and configured to stabilize a potential of the load, a first supply circuit which can supply electric power smaller than the predetermined amount to the capacitor and can discharge a charge from the capacitor, a second supply circuit which can supply electric power larger than the predetermined amount to the capacitor, a switch circuit configured to operate each of the first supply circuit and the second supply circuit, and a holding circuit configured to hold information based on the operation of the first supply circuit.
