LM4041BEX3-1.2+T

Overview

The LM4041BEX3-1.2+T is a precision two-terminal shunt voltage reference manufactured by Analog Devices (Maxim Integrated). It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.2% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60µA to 12mA and features low dynamic impedance. It is housed in a subminiature SC70-3 surface-mount package and is guaranteed to function over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

Ultra-small 3-pin SC70 surface-mount package for space-critical designs
Stable operation with any capacitive load without requiring external stabilizing capacitors
Low output noise of 20µVRMS (10Hz to 10kHz) for high-precision applications
Laser-trimmed resistors ensure precise initial accuracy across multiple grades

Applications

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

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) rather than the industrial range. Confirm the 'B' grade indicates the specific 0.2% initial accuracy requirement. Ensure the '+T' designation matches the required reel packaging format for automated assembly processes.

Selection Notes

Select this component when a fixed 1.225V reference is required in a compact footprint. The B-grade offers a balance between tight tolerance and cost compared to the A-grade. Verify that the application can maintain the minimum operating current of 60µA and does not exceed the maximum shunt current of 12mA during normal operation.

Part Context

This part belongs to the LM4041 family of micropower shunt voltage references. The family includes variants with different accuracies (A, B, C, D grades), packages (SC70-3, SOT23-3), and temperature ranges (I for industrial, E for extended). The LM4041 utilizes bandgap principles and laser trimming to achieve stability.
