LM9140 Precision Micropower Shunt Voltage Reference April 1998 LM9140 Precision Micropower Shunt Voltage Reference General Description The LM9140’s reverse breakdown voltage temperature coefficients of ± 25 ppm/˚C are ideal for precision applications. The LM9140’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM9140 easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.500V, 4.096V, 5.000V, and 10.000V. The minimum operating current increases from 60 µA for the LM9140-2.5 to 100 µA for the LM9140-10.0. All versions have a maximum operating current of 15 mA.
