Abstract
A power supply circuit in an embodiment includes a series circuit of a first resistor and a second transistor, the series circuit being connected in parallel to a first transistor between an input terminal and an output terminal, a third transistor configured to output an electric current corresponding to an electric current flowing to the first resistor, a third resistor configured to generate a voltage corresponding to the electric current, and a second operational amplifier configured to output a signal corresponding to a voltage difference between the voltage and a reference voltage to a gate of the first transistor and a gate of the second transistor.
