LM4040BIM3-2.5/V+T

Overview

The LM4040BIM3-2.5/V+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 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 capability 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 while tolerating any capacitive load.
Low dynamic impedance maintains accurate reverse breakdown voltage over wide operating currents.
Automotive-grade qualification available for specific /V suffix variants.

Applications

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

Procurement Notes

Verify the /V suffix indicates AEC-Q100 automotive qualification when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated on official documentation. Ensure the ordering code matches the specified 2.500V output and 0.2% accuracy grade. Check for RoHS compliance status indicated by the plus sign in the part number.

Selection Notes

Select this variant when extended industrial temperature ranges up to +125°C are required alongside automotive reliability standards. The 0.2% accuracy grade offers a balance between precision and cost compared to tighter tolerance options. Verify that the 3-pin SOT23 package dimensions fit the target PCB layout constraints.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family includes various output voltages and accuracy grades. The /V suffix specifically denotes parts qualified to AEC-Q100 standards for automotive applications, distinguishing them from standard commercial or industrial versions.
