LM4051

Precision Micropower Shunt Voltage Reference

General Description

Low output noise

(10 Hz to 10kHz)

20µV_rms

60µA to 12mA

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 ad-

vanced 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 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.

Wide operating current range

Industrial temperature range

Extended temperature range

Low temperature coefficient

−40˚C to +85˚C

−40˚C to +125˚C

50 ppm/˚C (max)

Applications

n Portable, Battery-Powered Equipment

n Data Acquisition Systems

n Instrumentation

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 −40˚C to 125˚C.

n Process Control

n Energy Management

n Automotive and Industrial

n Precision Audio Components

n Base Stations

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 25˚C.

n Battery Chargers

n Medical Equipment

n Communication

Features

n Small packages: SOT-23

n No output capacitor required

n Tolerates capacitive loads

n Reverse breakdown voltage options of 1.225V and

adjustable
