LM4051
Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4051 precision
voltage reference is available in the sub-miniature (3 mm x
1.3 mm) SSOT-23 surface-mount package. The LM4051’s
advanced design eliminates the need for an external stabiliz-
ing capacitor while ensuring stability with any capacitive
load, thus making the LM4051 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 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 40C to 125C.
The LM4051 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 25C.
