    Abstract: A semiconductor circuit includes a first selection circuit which selects a first battery or a first capacitor, a second selection circuit which selects a second battery or a second capacitor, a voltage measuring circuit which measures a first voltage of the first battery or the first capacitor selected by the first selection circuit, and measures a second voltage of the second battery or the second capacitor selected by the second selection circuit, a controller which compares the first voltage and the second voltage to generate a comparison result, and a switching circuit which receives a signal based on a target output voltage, connects the first battery or capacitor selected by the first selection circuit, and the second battery capacitor selected by the second selection circuit in an interconnection relationship based on the comparison result to provide to an output terminal an output voltage responsive to the target output voltage.

    Abstract: Disclosed is an electronic device, which includes an amplifier circuit that receives a feedback voltage and a reference voltage and amplifies a difference between the feedback voltage and the reference voltage to output an amplified difference voltage, an analog-to-digital converter that converts the amplified difference voltage to a digital code including two or more bits, and low-dropout (LDO) regulators that outputs output voltages based on the digital code. Each of the LDO regulators includes power transistors outputting a corresponding output voltage of the output voltages, drives one of the power transistors in a switching state, and drives each of remaining power transistors in a turned-on state or a turned-off state.
