Abstract: A voltage regulator has an input terminal for receiving a supply voltage and an output terminal for providing a regulated voltage and a regulated current. Furthermore, the voltage regulator includes a regulator for generating the regulated voltage and the regulated current according to a regulation of the supply voltage. The regulator includes a plurality of regulation branches arranged between the input terminal and the output terminal, each one for providing an output voltage used for obtaining the regulated voltage and for providing an output current contributing to define the regulated current. The regulation branches are partitioned into a plurality of subsets each one including components adapted to operate within a corresponding maximum voltage different from the maximum voltage of the other subsets. In addition, the regulator includes a selector for selectively enabling the regulation branches according to an indicator of the supply voltage.
