According to the present embodiment, a power supply circuit includes a first transistor, a feedback voltage generation circuit, a first voltage generation circuit, and a protection circuit. The first transistor is connected between an input terminal and an output terminal. The feedback voltage generation circuit divides the output voltage to generate a feedback voltage. The first voltage generation circuit supplies a voltage to a first control terminal of the first transistor via a first node based on the feedback voltage and a reference voltage. The protection circuit outputs a voltage that makes the first transistor non-conducting or places the first transistor in a state where the first transistor has a predetermined high resistance value to the first control terminal, when the input voltage increases above a first threshold voltage within a predetermined time.
A power supply circuit comprising:
A semiconductor device that modulates a logic signal input to a signal input terminal and outputs a demodulated logic signal from a signal output terminal, comprising a power supply circuit configured to supply an output voltage used for driving, wherein the power supply circuit includes
A power supply circuit supplying an output voltage between a first terminal and a second terminal, comprising:
