Guide to Choosing the Best LDO for Your Application
LDOs are so common inside portable devices, state of the art power management integrated circuits (PMICs) for smartphones and other portable devices include over a dozen LDOs. To know which LDO you need, you must first define the application of your LDO and then examine which parameters are most important when dealing with that application. With so many different LDO applications and the multiple parameters that characterize a particular LDO, it is not easy to determine which LDO is best suited.
To help you figure this out, we have put together this reference. This guide presents a comprehensive list of all of the different LDO parameters with definitions, the most common applications of LDOs, and which parameters are critical for each.
