A voltage regulator includes a power transistor for providing an electrical current to a load circuit connected to an output of the regulator. The delivered current is limited by a limitation circuit within the regulator. A stabilization resistor is connected between the power transistor and the output of the regulator. The limitation circuit includes a fixed-voltage generator, and a comparator for comparing the voltage generated in the stabilization resistor by the output current of the regulator with the fixed voltage. The output of the comparator controls an adjustment transistor that limits the current delivered by the power transistor.
