  • AN-181 3-Terminal Regulator is Adjustable (Rev. B)
    PDF, 314 Кб, Версия: B, Файл опубликован: 5 май 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 Кб, Версия: A, Файл опубликован: 5 май 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.

  • Packaging Limits Range of Linear Regulators
    PDF, 75 Кб, Файл опубликован: 8 май 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.
