- 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. - AN-1148 Linear Regulators: Theory of Operation and Compensation (Rev. B)PDF, 300 Kb, 修订版: B, 档案已发布: May 6, 2013
This application note discusses the operation and compensation of linear regulators. - Understanding the Terms and Definitions of LDO Voltage RegulatorsPDF, 197 Kb, 档案已发布: Oct 21, 1999
This report provides an understanding of the terms and definitions of low dropout (LDO) voltage regulators and describes fundamental concepts including dropout voltage quiescent current standby current efficiency transient response line/load regulation power supply rejection output noise voltage accuracy and power dissipation. Each section includes an example to increase the understandab - 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.
