In accordance with the switching operation of a switching section, current is made to flow from a battery to an inductor repeatedly. A voltage generated at the inductor is smoothed by a condenser and then input to a regulator. A D/A converter within a CPU monitors the input to the regulator, and an output voltage of the regulator stabilizes a reference voltage of the D/A converter.
