  Packaging Limits Range of Linear Regulators
  PDF, 75 Kb, File published: May 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.

  AN-181 3-Terminal Regulator is Adjustable (Rev. B)
  PDF, 314 Kb, Revision: B, File published: May 5, 2013
  Until now all of the 3-terminal power IC voltage regulators have a fixed output voltage. In spite of this limitation their ease of use low cost and full on-chip overload protection have generated wide acceptance. Now with the introduction of the LM117 it is possible to use a single regulator for any output voltage from 1.2 V to 37 V at 1.5A. Selecting close-tolerance outp

  Method For Cal Output Voltage Tolerances in Adj Regs (Rev. A)
  PDF, 284 Kb, Revision: A, File published: May 5, 2013
  When working with voltage regulator circuits the designer is often confronted with the need to calculatethe tolerance of the regulated output voltage. For fixed voltage regulators this problem is easily managedbecause the required information is directly supplied on the semiconductor manufacturer's data sheet.
