LM4040DEM3-2.5+T

Overview

The LM4040DEM3-2.5+T is a precision, two-terminal shunt mode bandgap 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 1.0% and a maximum temperature coefficient of 150ppm/°C. The device operates within a wide current range from 60μA to 15mA and supports an industrial temperature range of -40°C to +125°C. It is housed in a subminiature 3-pin SOT23 surface-mount package.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across multiple grades.
Low dynamic impedance maintains stable reverse breakdown voltage over varying operating currents.
Inherently stable without requiring external stabilizing capacitors for frequency stability.
Capable of tolerating any capacitive load directly at the output.

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 specifications such as temperature grade and package type. Confirm RoHS compliance status through the datasheet or component markings. Ensure the procurement channel sources genuine parts to avoid counterfeit components that may not meet the specified electrical characteristics.

Selection Notes

Select this component when a compact footprint is required alongside high precision. The D-grade offers 1.0% accuracy suitable for general-purpose applications. Verify that the circuit design accommodates the minimum operating current of 60μA and does not exceed the maximum shunt current of 15mA during operation.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family includes various voltage options and accuracy grades (A, B, C, D) packaged in both SC70 and SOT23 formats. The 'D' designation indicates the 1.0% accuracy tier, while the 'E' suffix denotes the extended industrial temperature range capability up to +125°C.
