Abstract
A step down unit steps down an external power supply voltage Vcc. A bias current control circuit controls the magnitude of bias current flowing through an auxiliary path connecting an output node and the ground. A system controller increases the magnitude of the bias current, prior to a change of the operation state of a load circuit by which a relatively large change occurs to the amount of current consumed by the load circuit including a central processing unit.
