LM4050CEM3X-10/NOPB

Voltage Reference Overview

The LM4050CEM3X-10/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed reverse breakdown voltage of 10 V. It operates within an extended temperature range of -40°C to 125°C and utilizes a compact SOT-23 package. The device guarantees a maximum initial accuracy of ±0.5% at 25°C and maintains a low temperature coefficient of 50 ppm/°C across the operating range. Electrical characteristics include a minimum operating current of 110 μA and a maximum operating current of 15 mA.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors 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 over wide temperature ranges

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and confirms compliance with RoHS directives as per the manufacturer's documentation. Ensure the ordering part number matches the required voltage option and tolerance grade. Confirm that the component meets the necessary automotive or industrial qualification standards if applicable to the design requirements.

Voltage Reference Selection Notes

Select this component when a fixed 10 V reference is required in a space-constrained surface-mount application. The C-grade offers a balance of cost and performance with ±0.5% accuracy. Consider the minimum operating current of 110 μA to ensure proper biasing in low-power circuits. Verify thermal management capabilities given the small SOT-23 package size.

Voltage Reference Part Context

This device belongs to the LM4050-N family of precision micropower shunt voltage references. The family provides multiple fixed voltage options including 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V.
