Abstract: A voltage regulator includes a first circuit to generate a difference signal based on an input reference voltage, a regulated output voltage, and a signal on a feedback node. The voltage regulator includes a second circuit to provide the regulated output voltage on the output node based on the difference signal. The second circuit includes a first transistor coupled to receive the difference signal, a first feedback circuit to provide a first feedback signal to the feedback node, and a second feedback circuit to provide a second feedback signal to the feedback node. An open loop frequency response of the voltage regulator has a first pole and a second pole and the first feedback signal may adjust the frequency of the second pole based on a load current. The second feedback signal may adjust loop gain based on the load current.
