A regulating circuit for the output voltage of a voltage booster, of the type which comprises a first charge transfer capacitor adapted to draw electric charges from the supply terminal and transfer them to the output terminal, through electronic switches controlled by non-overlapped complementary phase signals, and a second charge storage capacitor connected between the output terminal and ground, further comprises an error amplifier which generates, during one of the operational phases, a DC voltage corresponding to the difference between a reference voltage and a divided voltage of the output voltage of the voltage booster; this DC voltage is applied directly to one end of the transfer capacitor./!
