Abstract: A voltage regulator has a switching circuit and a control circuit. The switching circuit receives an input voltage and provides an output voltage and an output current. The control circuit provides a control signal to the switching circuit, such that the output voltage is maintained at a clamp voltage level when the output current is lower than a transition current level, and the output voltage decreases as the output current increases when the output current is higher than the transition current level.
