This thesis discusses different analog LDO topologies and analyzes how they achieve stability using small signal analysis and related equations. The power supply rejection (PSR) of a different error amplifier and pass device has been analyzed and concluded that a Type-B amplifier with n-channel metal oxide semiconductor field effect transistor (MOSFET) output stage or a Type-A amplifier with p channel MOSFET (PMOS) output stage yields the best PSR.

The digital LDO regulator is intriguing due to its low power and synthesizability, but it suffers from coarse voltage regulation and poor PSR compared to the analog LDO regulator.","abstract_html":"The presented research analyses different topologies of low dropout (LDO) regulator, mostly focusing on different frequency compensation schemes and power supply rejection analysis.
