Abstract:
A voltage regulator apparatus includes a first power transistor and a second power transistor connected in parallel to each other between a first power source and a second power source, and a control unit for turning on the first power transistor and the second power transistor. An aspect ratio of the first power transistor is smaller than an aspect ratio of the second power transistor. The control unit turns on the second power transistor in a predetermined period of time after the first power transistor is turned on.
