Abstract
An embodiment of a semiconductor integrated circuit, which receives a power supply voltage at an input terminal and outputs a feedback voltage for controlling a level of the power supply voltage, includes a feedback voltage generating unit that generates the feedback voltage corresponding to the level of the power supply voltage at the input terminal. The feedback voltage generating unit includes a variable resistance element. A resistance control unit controls the resistance value of the variable resistance element to account for changes in a desired target level for the power supply voltage.
