Abstract
A system-on-chip according to an embodiment includes a core including a header switch circuit configured to transmit a power supply voltage applied to a first power rail as a supply voltage to a second power rail and a logic circuit configured to operate based on the supply voltage from the second power rail, and a low-dropout (LDO) regulator configured to regulate a magnitude of first current output to the second power rail based on a change in the supply voltage, wherein the LDO regulator is further configured to control on/off of a plurality of first header switches included in the header switch circuit based on an amount of the change in the supply voltage.
