Method For Cal Output Voltage Tolerances in Adj Regs (Rev. A)
PDF, 284 Kb, 修订版: A, 档案已发布: 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.

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, 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.
