Abstract
A voltage limiter for a voltage regulator includes two comparison paths, each with a transistor. One comparison path is coupled to a reference voltage, the other is coupled to the regulator output. The limiter includes a resistor in a path between the control terminals of the two transistors to provide a voltage drop in response to current flowing through the resistor. The second comparison path includes a trigger node whose voltage controls the conductivity of a shunt transistor for shunting current from the regulator output. The voltage limiter includes a current control circuit for controlling a current through the resistor to generate the voltage drop across the resistor, wherein the current control circuit adjusts the current through the resistor to control the voltage drop based on a voltage of the trigger node.
