A power supply circuit comprising: a voltage generating circuit configured to generate an output voltage of a target level from an input voltage; an overcurrent protection circuit configured to control the voltage generating circuit so as to stop an output current, when a level of the output current generated at a time of generating the output voltage is greater than a reference level; and a reference-level change circuit configured to change the reference level in the overcurrent protection circuit to be at a second level higher than a first level from the first level for a predetermined period, when the overcurrent protection circuit detects that the level of the output current is greater than the reference level.
