摘要： A method to maintain stability of a low drop-out (LDO)/load switch linear voltage regulator (LVR). The method includes determining, during a power-up phase and by a capacitance sensing circuit, an estimated output capacitance value at an output node of the LDO/load switch LVR, and adjusting, based on the estimated output capacitance value, an adaptive RC network in the LDO/load switch LVR, wherein the adaptive RC network produces an adaptive zero in a feedback network transfer function of the LDO/load switch LVR, wherein the adaptive zero reduces an effect of a non-dominant pole in the open loop transfer function of the LDO/load switch LVR, and wherein a frequency of the adaptive zero is inversely proportional to the estimated output capacitance value.
