Abstract: A voltage regulator (40; 50) for a regulated voltage generator (2) configured for generating an operating voltage (V OUT ), the voltage regulator comprising: a variable comparison voltage generator (42), configured for generating on an output (48c) of its own a comparison voltage (V C ); a partition branch (44; 52) including a plurality of active devices (T 1 , ..., T M-1 , T M ) of a resistive type, configured for receiving at input the operating voltage (V OUT ) and supplying at output an intermediate voltage (V R ) correlated to the operating voltage; and a comparator (46), configured for receiving at input the comparison voltage (V C ) and the intermediate voltage (V R ) and supplying at output a regulation signal (V ON/OFF ) for the regulated-voltage generator (2).
