8.1 Overview

The LM4051-N is a precision voltage reference available in SOT-23 surface mount package. The LM4051-N is available in a 1.225 V fixed-option as well as an adjustable voltage option. The LM4051-N comes in three different tolerance 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 temperature coefficient of 50 ppm/˚C guaranteed from −40˚C to 125˚C.
