LM4041CEX3-1.2+T

Overview

The LM4041CEX3-1.2+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.5% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60µA to 12mA, featuring low dynamic impedance and output noise of 20µVRMS (10Hz to 10kHz). It is housed in a subminiature 3-pin SC70 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
Laser-trimmed resistors ensure precise initial accuracy across multiple grades
Low dynamic impedance maintains stable voltage accuracy over wide operating currents

Applications

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

Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) rather than the industrial range. Confirm the 'C' grade designation corresponds to the required 0.5% initial accuracy specification. Ensure the 'X3' suffix matches the required SC70-3 package footprint and verify the '+T' indicates tape-and-reel packaging format.

Selection Notes

Select this component when a compact form factor is required alongside high precision. The 0.5% accuracy grade offers a balance between cost and performance compared to tighter tolerances. Ensure the application circuit maintains the shunt current between 60µA and 12mA to guarantee specified stability and noise characteristics.

Part Context

This part belongs to the LM4041 family of improved precision micropower shunt voltage references. It utilizes bandgap principles to generate a stable 1.225V output. The specific model combines the C-grade accuracy with the E-series extended temperature rating and X3 SC70 packaging, distinguishing it from SOT23 or industrial temperature variants.
