Abstract
A power supply circuit configured to generate an output voltage at a target level from an input voltage thereof. The power supply circuit includes a wiring configured to receive the input voltage, a variable resistor provided between the wiring and a predetermined node, a voltage generation circuit configured to apply a voltage at a predetermined level to the predetermined node based on a current from the variable resistor, an output circuit configured to output the output voltage at the target level, in response to the voltage at the predetermined level being applied to the predetermined node, and an adjustment circuit configured to increase a resistance value of the variable resistor in response to a predetermined time period having elapsed since starting of generation of the output voltage.
