Understanding LDO Dropout

Texas Instruments

Published Date: 05/09/2005

Description

Not all low dropout (LDO) linear regulator data sheets provide the voltage dropout information needed for all applications. This application report shows a designer how to use an LDO data sheet's specified dropout performance to determine the dropout voltage at other operating conditions.
