LM4051 LM4051 Precision Micropower Shunt Voltage Reference Literature Number: SNOS491C LM4051
Precision Micropower Shunt Voltage Reference
General Description j Low output noise Ideal for space critical applications, the LM4051 precision
voltage reference is available in the sub-miniature (3 mm x
1.3 mm) SOT-23 surface-mount package. The LM4051’s advanced design eliminates the need for an external stabilizing
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 adjustable reverse breakdown voltage. The minimum operating
current is 60 ВµA 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/ЛљC guaranteed from -40ЛљC to 125ЛљC.
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 В± 0.1% (A grade) at 25ЛљC. Features Small packages: SOT-23
