    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

    The LM340-XX are three terminal 1.0A positive voltage regulators with preset output voltages of 5.0V or15V. The LM340 regulators are complete 3-terminal regulators requiring no external components fornormal operation. However by adding a few parts one may improve the transient response provide for avariable output voltage or increase the output current. Included on the chip are all of t

  • 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.
