Abstract
A regulating device for receiving a variable voltage and delivering a constant voltage includes a regulating element that includes a circuit for comparing the variable voltage with a reference voltage, a circuit for dividing the variable voltage by a factor, and a switching circuit for supplying the regulating element with a voltage equal either to the variable voltage or to the divided variable voltage. The switching circuit may be controlled by the comparison circuit in such a way that the regulating element is supplied with the variable voltage if a voltage condition is not satisfied and with the divided variable voltage if the voltage condition is satisfied.
