    CPC classification number: G05F1/575

    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.

    Abstract: A digital low-dropout (LDO) regulator may include: an LDO core configured to select a control mode based on a state of an output voltage of the digital LDO regulator provided to a load block and to output a control code based on the control mode; and a plurality of power transistors configured to control supply current supplied to the load block based on the control code. The control mode may include a first mode and a second mode for changing the supply current faster than in the first mode. The LDO core may be configured to perform a step-back operation to re-output a previous control code output at least one cycle ago and operate in the first mode based on the state of the output voltage corresponding to the first mode being detected while operating in the second mode.
