Application Notes
- Adjustable 3-Terminal Regulator for Low-Cost Battery Charging SystemsPDF, 104 Кб, Файл опубликован: 3 окт 2002
- AN-182 Improving Power Supply Reliability with IC Power Regulators (Rev. B)PDF, 82 Кб, Версия: B, Файл опубликован: 5 май 2013
This application report discusses improving power supply reliability with IC power regulators. - AN-181 3-Terminal Regulator is Adjustable (Rev. B)PDF, 314 Кб, Версия: B, Файл опубликован: 5 май 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. Selecting close-tolerance outp - AN-1028 Maximum Power Enhancement Techniques for Power Packages (Rev. B)PDF, 684 Кб, Версия: B, Файл опубликован: 6 май 2013
The purpose of this application report is to aid the user in maximizing the power handling capability of Texas Instruments power packages by using the SOT-223 as an example. - Method For Cal Output Voltage Tolerances in Adj Regs (Rev. A)PDF, 284 Кб, Версия: A, Файл опубликован: 5 май 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-103 LM340 Series Three Terminal Positive Regulators (Rev. A)PDF, 814 Кб, Версия: A, Файл опубликован: 6 май 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 - AN-1148 Linear Regulators: Theory of Operation and Compensation (Rev. B)PDF, 300 Кб, Версия: B, Файл опубликован: 6 май 2013
This application note discusses the operation and compensation of linear regulators. - Understanding the Terms and Definitions of LDO Voltage RegulatorsPDF, 197 Кб, Файл опубликован: 21 окт 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.

- Packaging Limits Range of Linear RegulatorsPDF, 75 Кб, Файл опубликован: 8 май 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. - A Topical Index of TI LDO Application Notes (Rev.
