Abstract:
A linear power supply circuit according to the present invention is provided with: an output transistor provided between an input end to which an input voltage is applied and an output end to which an output voltage is applied; a driver for driving the output transistor; and a feedback unit for feeding, back to the driver, information about an output electrical current that is output from the output end. The driver drives the output transistor on the basis of the difference between a voltage based on the output voltage and a reference voltage, as well as the information.
