DESCRIPTION
Ideal for space critical applications, the LM4050-N
precision voltage reference is available in the sub-
miniature (3 mm x 1.3 mm) SOT-23 surface-mount
package. The LM4050-N design eliminates the need
for an external stabilizing capacitor while ensuring
stability with any capacitive load, thus making the
LM4050-N easy to use. Further reducing design effort
is the availability of several fixed reverse breakdown
voltages: 2.048V, 2.500V, 4.096V, 5.000V, 8.192V,
and 10.000V. The minimum operating current
increases from 60 μA for the LM4050-N-2.0 to 100
μA for the LM4050-N-10.0. All versions have a
maximum operating current of 15 mA.
The LM4050-N utilizes fuse and zener-zap reverse
breakdown voltage trim during wafer sort to ensure
that the prime parts have an accuracy of better than
±0.1% (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.
All grades and voltage options of the LM4050-N are
available in both an industrial temperature range
(−40°C and +85°C) and an extended temperature
range (−40°C and +125°C).
