Abstract
A three-terminal series regulator achieves high efficiency by using an enhancement mode P-channel or N-channel FET for the series regulating element, respectively, for positive or negative voltage regulation thereby eliminating the need for a boost voltage and also minimizing the input-to-output voltage differential at high power levels. Short circuit protection is provided using output voltage and current foldback.
