Abstract: A system-on-chip (SoC) includes a processor connected to a plurality of switches that are configured to adjust a supply voltage to the processor, a regulator configured to apply a control signal for controlling at least one of the plurality of switches, and a voltage droop detector connected to the regulator and the processor and configured to transmit a voltage droop detection signal to the regulator when a voltage droop is detected from the processor. The regulator may turn on a predetermined number of switches, among the plurality of switches, based on the control signal when receiving the voltage droop detection signal.

Abstract: A low dropout (LDO) regulator includes comparison circuitry configured to generate a comparison result signal by comparing a target voltage with an output voltage corresponding to an output voltage of an output terminal connected to an integrated circuit, voltage increase/decrease detection circuitry configured to generate a detection result signal by detecting whether the output voltage increases or decreases, control circuitry configured to generate a current control code having a value that is changed, based on a control mode selected according to the comparison result signal and the detection result signal, and current driving circuitry configured to receive the current control code and generate an output current corresponding to the current control code.
