The present disclosure relates to a voltage regulation apparatus, a chip and an electronic device. The apparatus comprises: a voltage output module; a first voltage generation module; a second voltage generation module; a voltage regulation module used for regulating a first comparison voltage according to an input voltage so that the first voltage generation module outputs a regulated first comparison voltage, or regulating a second comparison voltage according to the input voltage so that the second voltage generation module outputs a regulated second comparison voltage; and a control signal generation module used for outputting a control signal according to the regulated first comparison voltage or the regulated second comparison voltage, so that the voltage output module obtains an output voltage according to the control signal and the input voltage. The apparatus of the present disclosure can quickly respond to the change of the input voltage, regulate the control signal and improve the line voltage transient response, so that the voltage output module can still provide a stable output when the input voltage changes.
