3 Description
Ideal for space-critical applications, the LM4041-N
precision voltage reference is available in the sub-
miniature SC70 and SOT-23 surface-mount
packages. The advanced design of the LM4041-N
eliminates the need for an external stabilizing
capacitor while ensuring stability with any capacitive
load, thus making the LM4041-N easy to use. Further
reducing design effort is the availability of a fixed
(1.225 V) and adjustable reverse breakdown voltage.
The minimum operating current is 60 μA for the
LM4041-N 1.2 and the LM4041-N ADJ. Both versions
have a maximum operating current of 12 mA.
The LM4041-N uses fuse and Zener-zap reverse
breakdown or reference 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.
