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. - Linear power for automated industrial systemsPDF, 1.8 Mb, File published: Jan 9, 2015
Designing a robust power management system for industrial automated equipment requires thorough understanding of the surroundings and conditions that affect the functionality. During the past few decades industrial and factory automation systems have become more robust intelligent and connected which has drastically increased the footprint for semiconductor components. This change has created a - AN-1148 Linear Regulators: Theory of Operation and Compensation (Rev. B)PDF, 300 Kb, Revision: B, File published: May 6, 2013

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, File published: Oct 21, 1999

Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changingload transients and also bypass very high frequency noise coming from switching converter powersources which a linear regulator can not reject. However using ultra-low ESR capacitors on the output ofan LDO regulator requires that specific design changes be implemented to ensure loop stabili - Packaging Limits Range of Linear RegulatorsPDF, 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.
