3 Description
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 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.
