Shunt Voltage Reference Integrated Circuit IC Chip 15mA SOT-23-3 LM4040AIM3-2 LM4040

LM4040AIM3-2 LM4040 Shunt Voltage Reference IC ±0.1% 15mA SOT-23-3

Description

Ideal for space-critical applications, the LM4040-N precision voltage reference is available in the subminiature SC70 and SOT-23 surface-mount package. The advanced design of the LM4040-N eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4040-N easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. The minimum operating current increases from 60 μA for the 2.5-V LM4040-N to 100 μA for the 10-V LM4040-N. All versions have a maximum operating current of 15 mA. The LM4040-N uses a 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 breakdown voltage accuracy over a wide range of operating temperatures and currents. Also available is the LM4041-N with two reverse breakdown voltage versions: adjustable and 1.2 V.
