【 摘 要 】

This thesis aims to construct a modular low-dropout regulator that gives designers more freedom in building a highly efficient regulator that meets application demands. This modular design is able to separate DC regulation and high-frequency supply rejection while not compromising on either of the two. Flexibility is a key requirement during both design and post-design. The proposed regulator is able to achieve all the required goals with full spectrum power supply rejection. By splitting the pass device, this design is able to achieve the best of both internal pole dominant and external pole dominant linear regulators.
