Intersil: Understanding Linear Regulators and Their Key Performance Parameters

May 18, 2016 // By Intersil Corp.
Low-dropout regulators (LDOs) are often used as a generally simple and inexpensive way to control an output voltage that is delivered from a higher input voltage supply. However, datasheets do not list the parameters for every possible circuit condition and designers need to determine whether an LDO is suitable for a specific load by analyzing the surrounding circuit conditions. This article will examine key performance parameters of LDOs and the factors a designer must consider to optimize a system.
