A linear power supply circuit includes an output transistor provided between an input terminal to which an input voltage is applied and an output terminal to which an output voltage is applied, and a driver configured to drive the output transistor based on the difference between a voltage based on the output voltage and a reference voltage. The driver includes a differential amplifier, a converter, and a first capacitor provided between the output of the differential amplifier and a ground potential. The linear power supply circuit further includes a source follower circuit including a first transistor, and moreover includes a second transistor connected in series with the output transistor and constituting together with the first transistor a current mirror circuit, and a second capacitor connected to the control terminal of the first transistor.
