应用须知
- Simple Power Solution Using LDOs for the DM365 (Rev. A)PDF, 104 Kb, 修订版: A, 档案已发布: Sep 11, 2009
- 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. - Technical Review of Low Dropout Voltage Regulator Operation And PerformancePDF, 284 Kb, 档案已发布: Aug 30, 1999
This application report provides a technical review of low dropout (LDO) voltage regulators and describes fundamental concepts including dropout voltage quiescent current and topologies. The report also includes detailed discussions of load/line regulation efficiency frequency response range of stable ESR and accuracy of LDO voltage regulators. - Ceramic Capacitors Replace Tantalum Capacitors in LDOs (Rev. A)PDF, 44 Kb, 修订版: A, 档案已发布: Oct 13, 2006
With the proper considerations ceramic output capacitors can be used with low dropout regulators (LDO) and DC/DC switching converters that require tantulum output capacitors. - Digital Designer's Guide to Linear Voltage Regulators & Thermal Mgmt (LDO) (Rev. A)PDF, 509 Kb, 修订版: A, 档案已发布: Jun 4, 2008

This reference design is presented to help application designers and others who are trying to use the MSP430 in a system with an input voltage in the range of 3.6 V to 5.5 V and who are also interested in using an easy-to-use low-dropout linear regulator (LDO) for a simple design but may not be as concerned about maintaining the highest possible efficiency or longest battery life. - ESR Stability and the LDO RegulatorPDF, 83 Kb, 档案已发布: May 7, 2002
Choosing an output capacitor for LDO regulators with PNP or PMOS pass element can be difficult to specific ESR requirements. This application note explains why higher ESR capacitors are necessary how to chose them and how to determine whether or not the regulator is stable. - Understanding LDO DropoutPDF, 52 Kb, 档案已发布: May 9, 2005
Not all low dropout (LDO) linear regulator data sheets provide the voltage dropout information needed for all applications. This application report shows a designer how to use an LDO data sheet's specified dropout performance to determine the dropout voltage at other operating conditions. - Extending the Input Voltage Range of an LDO RegulatorPDF, 32 Kb, 档案已发布: Aug 16, 2002
