LM4050BEM3-5.0/NOPB

Voltage Reference Overview

The LM4050BEM3-5.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy tolerance of ±0.2%. The device features a temperature coefficient of 50ppm/°C and supports a maximum shunt current of 15mA. It operates within a temperature range of -40°C to +125°C and utilizes a SOT-23-3 surface-mount package.

Voltage Reference Feature Summary

• Precision bandgap voltage reference with laser-trimmed resistors for high initial accuracy
• Capable of handling wide operating currents from microamps to 15mA without external stabilization capacitors
• Designed for stability across a broad industrial temperature range

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered systems needing low power consumption
• Data acquisition systems requiring stable analog-to-digital converter references

Voltage Reference Procurement Notes

Verify the specific suffix 'B' against official Texas Instruments documentation to confirm the exact accuracy grade, as standard LM4050 variants often specify 0.5% or 0.2% tolerances. Ensure the component meets AEC-Q100 requirements if automotive qualification is necessary for the target application environment.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference is required in a compact SOT-23-3 footprint. Consider the 50ppm/°C temperature coefficient and 15mA load capability against system power budget constraints. Verify that the ±0.2% initial accuracy aligns with the circuit's error budget requirements.

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references. These devices are designed to replace Zener diodes in applications requiring higher precision and lower noise. The family offers multiple fixed voltage options in subminiature packages suitable for space-constrained designs.

Voltage Reference Replacement Considerations

LM4050CEM3X-5.0/NOPB: Lower accuracy variant (±0.5%). TL4050B50IDBZR: Commercial grade alternative with similar electrical characteristics but different temperature range.
