A voltage regulator includes a switch configured to alternately couple and decouple a voltage source through a inductor to a load, a feedback circuitry configured to generate a feedback current proportional to a difference between a desired voltage and an output voltage at an output terminal, a current sensor configured to measure the feedback current, a controller configured to receive the feedback current level from the current sensor and, in response thereto, to control a duty cycle of the switch, and a current mirror configured to generate a reporting current proportional to the feedback current.
