Abstract
An amplifier drives the gate of a master source follower and of at least one slave source follower to form a low-dropout (LDO) regulator. Alternatively, a charge pump drives the master source follower to form the regulator. Additional slave source followers may be used in conjunction with the charge pump and the master source follower to improve the regulator performance.
