Abstract
A linear voltage regulator includes a Miller frequency compensation having a movable zero, which tracks the frequency of the load pole as the load condition changes. The compensated voltage regulator maintains stability under variable load conditions. Because of the Miller effect, DC open-loop gain and bandwidth are not sacrificed for stability. The compensated voltage regulator can therefore maintain high power supply rejection ratio (PSRR).
