摘要
A power circuit includes a power input port, a power output port, and a three-terminal regulator. A voltage regulating circuit and a charge/discharge circuit are connected to the power output port. The three-terminal regulator detects a voltage value of the output port and enables the input port if the detected voltage value is less than a predetermined voltage value and disables the input port if the detected voltage value is not less than the predetermined value. If the input port of the three-terminal regulator is enabled, the charge/discharge circuit is charged by the current provided by a power supply connected to the power input port. If the input port of the three-terminal regulator is disabled, the charge/discharge circuit discharges to an electronic device connected to the power output port with the voltage regulating circuit.
