应用须知
- Packaging Limits Range of Linear RegulatorsPDF, 75 Kb, 档案已发布: 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-1028 Maximum Power Enhancement Techniques for Power Packages (Rev. B)PDF, 684 Kb, 修订版: B, 档案已发布: May 6, 2013

- AN-181 3-Terminal Regulator is Adjustable (Rev. B)PDF, 314 Kb, 修订版: B, 档案已发布: 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.

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 - Understanding the Terms and Definitions of LDO Voltage RegulatorsPDF, 197 Kb, 档案已发布: Oct 21, 1999
