Abstract: A voltage-regulator circuit with a low voltage drop using a DMOS power transistor (PT) driven by a charge pump (CP) comprises two feedback loops: a first feedback loop having high gain and accuracy but low response speed, and a second feedback loop having a wide passband and fast response speed but low gain.
