Beschreibung
Zusammenfassung:The invention relates to a voltage-regulating circuit (1) comprising: - a voltage regulator (21), - a switch (22), - a first comparing circuit (23) for comparing the amplitude deviation between the input voltage (Ve) and the output voltage (Vs1) to a first threshold (Vrefl), - a second comparing circuit (24) for comparing the amplitude of the output voltage (Vs1) to a second threshold (Vref2), and - a control circuit (25) for commanding the switch (22) to open or close depending on the comparisons made by the first comparing circuit (23) and by the second comparing circuit (24). The invention also relates to a regulated power-supply module comprising such a regulated circuit (1). ri / r4n NNe Fig. Fig.1
