ABSTRACT:
A voltage regulator for powering a load with a predetermined temperature-stable voltage, including an output stage, a terminal of which provides a current to the load, at a reference voltage; and a current source including a first branch formed of transistors and of a first resistor connected in series between two supply terminals, and a second branch formed of transistors connected in series between the two supply terminals, the output stage including a bipolar transistor connected as a current mirror with a bipolar transistor of the second branch, and the two transistors of the current source are crossed.
