Abstract:
1. A power supply apparatus, comprising: a monitor unit configured to monitor an input voltage of a DC power supply; a reset signal circuit configured to output a reset signal to an integrated circuit to which an electric power is supplied when the input voltage monitored by said monitor unit falls below a predetermined threshold value; a power supply circuit configured to stop supply of the electric power to the integrated circuit in synchronism with outputting of the reset signal; and a dummy element, connected to a line between said power supply circuit and the integrated circuit, wherein said dummy element is enabled based on reception of the reset signal, and a value of an electric current from said power supply circuit caused by enablement of said dummy element decreases from a first value to a second value, and the value decreases from the second value to a third value after an elapse of a predetermined time.
