Abstract
Official abstract text for this publication.
A voltage regulator circuit includes a plurality of transistors and a control circuit. Each transistor has two source/drain terminal and a gate terminal. One source/drain terminal of each transistor is electrically coupled to a source voltage, and the other source/drain terminals of the transistors are electrically coupled to each other and corporately referred to as an output terminal of the voltage regulator circuit. The control circuit is electrically coupled to the gate terminals of the transistors and configured to determine the number of the transistors to be turned on according to the difference between the voltage at the output terminal and a predetermined reference voltage.
