3 Description
Ideal for space-critical applications, the LM4040-N
precision voltage reference is available in the sub-
miniature 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.
See the LM4041-N data sheet (SNOS641).
