LM4050CEM3X-4.1/NOPB

Voltage Reference Overview

The LM4050CEM3X-4.1/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed reverse breakdown voltage of 4.096 V. It operates within an extended temperature range of -40°C to +125°C and utilizes a compact SOT-23 surface-mount package. The device guarantees an initial accuracy of ±0.5% at 25°C with a maximum temperature coefficient of 50 ppm/°C. Designed for stability without external capacitors, it supports a cathode current range from a minimum of 78 μA up to a maximum of 15 mA.

Voltage Reference Feature Summary

Eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load
Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy
Bandgap reference temperature drift curvature correction ensures stable performance across wide operating temperatures

Voltage Reference Applications

Portable, battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Voltage Reference Procurement Notes

Verify the specific suffix 'CEM3X' corresponds to the C-grade (±0.5%) tolerance and extended temperature rating (-40°C to 125°C) required for your design. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering information matches the exact voltage option of 4.096 V to avoid functional mismatches in shunt regulator circuits.

Voltage Reference Selection Notes

Select this component when space constraints require a sub-miniature SOT-23 package. Choose this part if the application demands a fixed 4.096 V reference with moderate precision (±0.5%) rather than the higher A-grade accuracy. It is suitable for designs requiring operation up to 125°C ambient temperature where low quiescent current consumption is beneficial.

Voltage Reference Part Context

This device belongs to the LM4050-N family of precision micropower shunt voltage references. The family offers various fixed voltage options including 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V. The LM4050-N series is designed to replace larger packages while maintaining high precision and low power consumption characteristics essential for modern portable electronics.
