Abstract
Provided is an electronic device including a power supply circuit. The power supply circuit includes: a voltage driving unit configured to pull-up drive an output node and generate an output voltage; and a driving control unit configured to receive the output voltage, disable the voltage driving unit from the time at which a divided voltage obtained by dividing the output voltage at a set ratio becomes higher than a first level, and enable the voltage driving unit from the time at which the divided voltage becomes lower than a second level, which is higher than the first level.
