ABSTRACT:
A voltage regulator for memory circuits has a differential stage having a non-inverting input terminal receiving a control voltage independent of the temperature; an inverting input terminal connected to a ground voltage reference; a feed terminal connected to a booster circuit adapted for producing a boosted voltage; and an output terminal connected to an output terminal of the voltage regulator, for producing an output voltage reference starting from the comparison of input voltages. The voltage regulator further comprises a connecting transistor inserted between the feed terminal and the output terminal of the differential stage, the connecting transistor being source follower having a control terminal connected to the output terminal of the differential stage, as well as a source terminal connected to the output terminal of the voltage regulator, in such a way as to self-limit the transition of the voltage on the output terminal.
