Abstract:
A voltage regulator includes a driving circuit, a feedback circuit, first and second control circuits and a resistor. The driving circuit is coupled to an input node and an output node and generates an output voltage at the output node from an input voltage at the input node. The feedback circuit is coupled to the output node and generates a feedback voltage based on the output voltage. The first control circuit is coupled to the feedback circuit and the driving circuit to control the output voltage based on the feedback voltage. The resistor has opposite first and second terminals. The first terminal of the resistor is coupled to the output node. The second control circuit is coupled to the second terminal of the output stage resistor and the feedback circuit to control the feedback voltage based on a regulated voltage at the second terminal of the resistor.
