摘要：
A voltage regulator for a DC power supply senses the current in the return line of the power supply and compares the sensed current to a threshold that is generated within the regulator section of the power supply. When the sensed current exceeds the threshold, a detector circuit will sense the threshold being exceeded and override the voltage control circuit that is used to regulate the DC power supply and reduce or remove the output voltage until the sensed current falls below the threshold level. The current limiting action is preformed by controlling the conductance of the pass element so that the pass element is always operating within its safe operating area.
