Abstract: A fast-transient buffer is shown. The fast-transient buffer has a flipped voltage follower coupled between the input terminal and the output terminal of the fast-transient buffer, and a first MOS transistor coupled to the flipped voltage follower as well as the output terminal of the fast-transient buffer. The first MOS transistor regulates the output voltage of the output terminal of the fast-transient buffer, in the opposite direction in comparison with an output voltage regulation direction due to the flipped voltage follower.
