Abstract
A linear power supply circuit includes: an output stage provided between an input terminal to which an input voltage is applied and an output terminal to which an output voltage is applied and including a first output transistor and a second output transistor connected in parallel with each other; a driver configured to drive the first and second output transistors based on the difference between a voltage based on the output voltage and a reference voltage; and a potential difference suppressor configured to suppress a potential difference between the control terminal of the first output transistor and the control terminal of the second output transistor.
