A switching voltage regulator circuit for converting an input voltage signal to a regulated DC output voltage signal to be applied to a load is provided. According to one embodiment, the circuit comprises a switching device receiving the input voltage signal and having an output being coupled to an output filter generating the regulated output voltage signal; a current limiting device sensing current drawn by said load to generate a current error signal whenever the current exceeds a predetermined current limit value; a voltage comparator amplifier receiving the regulated output voltage signal and the current error signal and comparing thereof to a reference voltage to generate a voltage error signal; and a switching control device receiving the voltage error signal to generate a control signal for the switching device.
