Abstract
A regulator circuit comprising an input for receiving an input voltage; an output stage, configured to switch between said input voltage and a reference voltage to generate an output voltage, in dependence on a modulated signal; a controller, configured to receive an error signal (V) on a control input and to provide the modulated signal to said output stage; an error amplifier, for providing the error signal to the controller in dependence on the output voltage; and presetting circuitry, configured to estimate the error signal in dependence on at least the input voltage, and for presetting the control input with the estimated error signal.
