ABSTRACT:
There is provided a power source apparatus that includes a master circuit and a slave circuit provided in parallel and outputs an electric current that adds an electric current output from the master circuit and an electric current output from the slave circuit as a power-supply current. The master circuit includes: a main circuit side output section operable to output an electric current depending on a given voltage; a main circuit side reference power source operable to generate a reference voltage corresponding to a power-supply voltage that the power source apparatus is to output; and a main circuit side control section operable to supply the voltage corresponding to the reference voltage to the main circuit side output section in order to control the current output from the main circuit side output section. The slave circuit includes a sub-circuit side output section operable to receive a voltage based on the electric current output from the main circuit side output section and to output an electric current depending on the voltage, the sub-circuit side output section having the same characteristic as that of the main circuit side output section.
