LM4040Precision Micropower Shunt Voltage ReferenceGeneral DescriptionIdeal for space critical applications,the LM4040precision voltage reference is available in the sub-miniature SC70and SOT-23surface-mount package.The LM4040’s advanced design eliminates the need for an external stabilizing capaci-tor while ensuring stability with any capacitive load,thus making the LM4040easy to use.Further reducing design effort is the availability of several fixed reverse breakdown voltages:2.048V,2.500V,3.000V,4.096V,5.000V,8.192V,and 10.000V.The minimum operating current increases from 60µA for the LM4040-2.5to 100µA for the LM4040-10.0.All versions have a maximum operating current of 15mA.The LM4040utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1%(A grade)at 25˚C.Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse break-down voltage accuracy over a wide range of operating tem-peratures and currents.Also available is the LM4041with two reverse breakdown voltage versions:adjustable and 1.2V.Please see the LM4041data sheet.Featuresn Small packages:SOT-23,TO-92and SC70n No output capacitor requiredn Tolerates capacitive loadsn Fixed reverse breakdown voltages of 2.048V,2.500V,3.000V,4.096V,5.000V,8.192V,and
