ABSTRACT:
A variable load current supply unit supplies a current to be consumed by a constant voltage output unit to a power source terminal thereof, and supplies a current to be consumed by a load circuit thereto through a reference voltage output terminal. The constant voltage output unit maintains a potential of the power source terminal thereof, i.e., a potential of the reference voltage output terminal, at a fixed potential. A base potential control unit negatively feeds back changes in the potential on the reference voltage output terminal to a base of an emitter follower transistor in the variable load current supply unit. In this way, when the current consumed by the load current is reduced and the potential on the reference voltage output terminal thereby slightly increases the current supplied by the variable load current supply unit decreases.
