Abstract: An electronic device for controlling voltage and a method therefor are provided. The electronic device includes a power regulator, a connector including one or more signal terminals and one or more power terminals electrically connected to the power regulator, and a control circuit electrically connected to the one or more signal terminals. The control circuit is configured to identify a type of an external electronic device connected through the connector, identify detected values for at least some of the one or more signal terminals based at least on the identified type corresponding to a predetermined type, and output, through the power regulator, a predetermined voltage to the external electronic device through the one or more power terminals based at least on the detected value being within a first predetermined range.
