Apparatus for voltage regulation circuits and related operating methods are provided. An exemplary voltage regulation circuit includes a voltage regulation arrangement that provides a regulated output voltage based on an input voltage reference, a phase compensation arrangement coupled to the voltage regulation arrangement and configured to increase a phase margin of the voltage regulation arrangement, and detection circuitry coupled to the phase compensation arrangement. The detection circuitry is configured to disable the phase compensation arrangement in response to detecting an output current that is less than a threshold value.
