Designed for space critical applications, the LM4051-N precision voltage reference is available in the sub-miniature (3mm x 1.30mm) SOT-23 surface mount package. The LM4051-N’s advanced design eliminates the need for an external stabilizing capacitor while maintaining 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 adjustable reverse breakdown voltage. The minimum operating current is 60µA for the LM4051-1.2 and the LM4051-ADJ. Both versions have a maximum operating current of 12mA.

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 designed for −40°C to 125̊°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.
