LM4051AIM3-ADJ/NOPB General Description

Ideal for space critical applications, the LM4051-N precision voltage reference is available in the sub-miniature (3 mm x 1.3 mm) SOT-23 surface-mount package. The LM4051-N’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4051-N easy to use. Further reducing design effort is the availability of a fixed (1.225V) and adjust- able reverse breakdown voltage. The minimum operating current is 60 µA for the LM4051-1.2 and the LM4051-ADJ. Both versions have a maximum operating current of 12 mA.

The LM4051-N comes in three grades (A, B, and C). The best grade devices (A) have an initial accuracy of 0.1%, while the B-grade have 0.2% and the C-grade 0.5%, all with a tempco of 50 ppm/ ̊C guaranteed from −40 ̊C to 125 ̊C.

The LM4051-N utilizes fuse and zener-zap trim of reference voltage during wafer sort to ensure that the prime parts have an accuracy of better than ± 0.1% (A grade) at 25 ̊C.
