Patent abstract
A low-drop out (LDO) regulator circuit is provided having a gate of a pass transistor coupled to an output of an operational transconductance amplifier, the LDO regulator exhibiting a non-dominant pole at an output of the LDO. A dynamic zero-compensation circuit is coupled in parallel to the pass transistor. A compensation control circuit is coupled and configured to adjust a frequency, at which a zero is generated, and cause the generated zero to track with the non-dominant pole.
