  Packaging Limits Range of Linear Regulators
  PDF, 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.
