LM4040BEM3-2.5+T

Overview

The LM4040BEM3-2.5+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.500V with an initial accuracy of ±0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It supports a shunt current range from 60μA to 15mA and utilizes a 3-pin SOT23 surface-mount package.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across multiple grades.
Stable operation without requiring external stabilizing capacitors for any capacitive load.
Low dynamic impedance maintains accurate reverse breakdown voltage over wide operating currents.

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C) compared to industrial variants. Confirm the '+T' designation corresponds to tape and reel packaging. Ensure the component matches the exact manufacturer part number to guarantee the specified 0.2% accuracy grade and SOT23 package type.

Selection Notes

Select this component when space constraints require a subminiature 3-pin package while maintaining high precision. The B-grade offers a balance of tight tolerance and low cost. Consider the minimum operating current requirement of 60μA for circuit design to ensure proper regulation under all load conditions.

Part Context

This device belongs to the LM4040 family of improved precision micropower shunt voltage references. The family includes various output voltages and accuracy grades (A, B, C, D). The 'E' suffix denotes the extended temperature version, while 'I' denotes the industrial temperature version. Both are available in SOT23 and SC70 packages.
