A linear voltage regulator includes a voltage-regulating circuit that controls a power transistor connected to a load. A current-limiting loop circuit includes a common input/output node that is coupled to a control electrode of the power transistor. The loop senses whether a current representative of the current flowing through the power transistor is above a reference current, and in response thereto delivers a non-zero output current to the control electrode of the power transistor. Otherwise, the loop does not deliver any output current to the control electrode of the power transistor.
