PROBLEM TO BE SOLVED: To provide a regulator circuit that can implement efficient current supply to a load circuit. SOLUTION: The regulator circuit includes a differential amplification circuit 30 for receiving a reference voltage VREF at an input terminal IT1 and receiving a regulation voltage VRG at an input terminal IT2 to amplify the voltage difference between the reference voltage VREF and the regulation voltage VRG, and an output circuit 40 connected with an output terminal DQ of the differential amplification circuit 30 to output the regulation voltage VRG. The output circuit 40 includes an N type output transistor TQ1 disposed between an output terminal RQ of the regulator circuit and a power supply VSS and connected at the gate thereof with the output terminal DQ of the differential amplification circuit 30, and a P type output transistor TQ2 disposed between a power supply HVDD and the output terminal RQ of the regulator circuit and connected at the gate thereof with the output terminal DQ of the differential amplification circuit 30.
