Claim Text:
1. A voltage regulator, comprising: an input node; an output node; a driving circuit coupled to the input node and the output node, the driving circuit configured to generate an output voltage at the output node from an input voltage at the input node; a feedback circuit coupled to the output node, the feedback circuit configured to generate a feedback voltage based on the output voltage; a first control circuit coupled to the feedback circuit and the driving circuit, the first control circuit configured to control the output voltage based on the feedback voltage; an output stage resistor having opposite first and second terminals, the first terminal of the output stage resistor coupled to the output node; and a second control circuit coupled to the second terminal of the output stage resistor and the feedback circuit, the second control circuit configured to control the feedback voltage based on a regulated voltage at the second terminal of the output stage resistor.
