Abstract: A system-on-chip includes a low-dropout (LDO) regulator configured to regulate a voltage of input power and to supply operation power to a core through an output mode, the core configured to receive the operation power to perform an operation, and a power supply circuit configured to supply the input power to the LDO regulator. The power supply circuit may receive first power and second power having different voltage characteristics, and may supply third power, which is power having a higher voltage of the first power and the second power, and the second power to the LDO regulator as the input power.
