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.
