This paper briefly introduces the developments of the fully-integrated low-dropout regulators (LDOs) at the beginning. Then, we use the classic proportional-integral-derivative (PID) control theory to discuss and categorize the existing LDOs, and present our design considerations for analog-digital hybrid LDOs in an intuitive way.
