This application report explains how to implement a low noise switch mode power supply solution. Itintroduces the sources of noise and explain how to minimize them. A big factor in noise generation andpropagation is the printed circuit board layout. Important basics are discussed. Circuit measurementtechniques are also explained to guide a design engineer towards a low noise but efficient so - LDO Noise Demystified (Rev.

The purpose of this application report is to aid the user in maximizing the power handling capability of Texas Instruments power packages by using the SOT-223 as an example. - AN-1482 LDO Regulator Stability Using Ceramic Output Capacitors (Rev. A)PDF, 169 Kb, Revisión: A, Archivo publicado: abr 25, 2013
Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changingload transients and also bypass very high frequency noise coming from switching converter powersources which a linear regulator can not reject. However using ultra-low ESR capacitors on the output ofan LDO regulator requires that specific design changes be implemented to ensure loop stabili - LDO Performance Near DropoutPDF, 149 Kb, Archivo publicado: oct 8, 2010
