Abstract: A device includes a first MOS transistor connected between first and second nodes, a selectively activatable current source connected between the second node and a third node and a circuit configured to control the first transistor to regulate a voltage at the second node to a first set point value. The device further includes a second MOS transistor connected between the first node and a fourth node, and having its gate connected to the gate of the first MOS transistor, a third MOS transistor connected between the third and fourth nodes, a switch connected between the second and fourth nodes, and another circuit configured to control the third transistor to regulate a voltage at the fourth node to a second set point value.
