This application note details the difference between LDO voltage regulators that use output capacitance and those that do not and how your system designs can benefit or be improved by not using an output capacitor. This document explains the difference between capless LDOs and those that require output capacitance. It also discusses the benefits and downsides of using output capacitance with your LDOs. How you can save money and board space by using capless LDO voltage regulators?
