3 Description
Excellent for space-critical applications, the LM4041-
N LM4041-N-Q1 precision voltage reference is
available in the sub-miniature SC70 and SOT-23
surface-mount packages. The advanced design of the
LM4041-N LM4041-N-Q1 eliminates the need for an
external stabilizing capacitor while providing stability
with any capacitive load, thus making the LM4041-N
LM4041-N-Q1 easy to use. Further reducing design
effort is the availability of a fixed (1.225V) and
adjustable reverse breakdown voltage. The minimum
operating current is 60μA for the LM4041-N LM4041-
N-Q1 1.2 and the LM4041-N LM4041-N-Q1 ADJ. Both
versions have a maximum operating current of 12mA.
The LM4041-N LM4041-N-Q1 uses fuse and Zenerzap
reverse breakdown or reference voltage trim
during wafer sort to make sure that the prime parts
have an accuracy of better than ±0.1% (A grade) at
25°C. Band gap reference temperature drift curvature
correction and low dynamic impedance provide stable
reverse breakdown voltage accuracy over a wide
range of operating temperatures and currents.
