LM9140 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.
The LM9140 utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.5% (B grade) at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.
