LM4040AEM3-2.5+T

Overview

The LM4040AEM3-2.5+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 0.1% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60μA to 15mA and supports an extended industrial temperature range of -40°C to +125°C. It utilizes a subminiature 3-pin SOT-23 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 or SOT23 surface-mount package for space-critical designs
Laser-trimmed resistors ensure high initial accuracy grades
Stable operation without external stabilizing capacitors across any capacitive load
Low dynamic impedance maintains accuracy over wide operating currents

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical tolerances, temperature ranges, and package types. Confirm RoHS compliance status and lead-free requirements prior to procurement. Ensure the selected variant matches the required operational environment and accuracy specifications.

Selection Notes

Select this component when precise voltage referencing is required in compact electronic designs. The 0.1% accuracy grade suits applications demanding tight tolerance limits. Verify that the circuit design accommodates the specified minimum operating current and maximum shunt current limits to maintain stable regulation under all expected load conditions.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The series offers multiple fixed reverse-breakdown voltages including 2.048V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in different accuracy grades ranging from 0.1% to 1.0% and temperature ranges extending up to +125°C.
