Abstract:
A semiconductor device includes a regulator including an operational amplifier configured of a current mirror and generating the second voltage V2 from a first voltage V1; and a control circuit that generates the current control signal OVDR, makes a current that is flowed by the current mirror increase by a first transition of the current control signal OVDR, and makes the current that is flowed by the current mirror decrease by a second transition of the current control signal OVDR. The control circuit includes a slew-rate processing unit that makes a second slew rate of the current control signal OVDR related to the second transition be smaller than a first slew rate of the current control signal OVDR related to the first transition.
