Each section includes an example to increase the understandab - 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 - Packaging Limits Range of Linear RegulatorsPDF, 75 Kb, Archivo publicado: mayo 8, 2010
The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential. This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.
