LM4050AEM3-2.0

Voltage Reference Overview

The LM4050AEM3-2.0 is a precision micropower shunt voltage reference manufactured by Texas Instruments, designed for applications requiring stable voltage regulation in compact form factors. This component provides a fixed output voltage of 2.0 V with an initial accuracy of ±0.1% and a temperature coefficient of 50 ppm/°C. It operates within a junction temperature range of -40°C to +125°C and supports a maximum cathode current of 15 mA. The device is housed in a SOT-23-3 surface-mount package, facilitating integration into space-constrained circuit designs while maintaining high performance standards.

Voltage Reference Feature Summary

• Provides precise micropower shunt voltage regulation with low noise characteristics
• Ensures high stability across wide temperature ranges with minimal drift
• Offers tight initial accuracy tolerance for sensitive analog signal processing

Voltage Reference Applications

• Portable battery-powered instrumentation systems
• Data acquisition and measurement equipment
• Microcontroller analog-to-digital converter references

Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific packaging variants such as cut tape or reel options before ordering. Check for end-of-life notices or obsolescence warnings, as availability may be limited. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Voltage Reference Selection Notes

Select this part when a fixed 2.0 V reference with high precision is required in a small footprint. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Evaluate power consumption constraints against the micropower design. Compare with adjustable alternatives if variable voltage outputs are needed instead of fixed references.

Voltage Reference Part Context

This component belongs to the LM4050-N series of precision voltage references from Texas Instruments. It shares architectural similarities with other shunt references like the LM4040 but offers improved accuracy and lower temperature coefficients. The series is widely used in industrial and consumer electronics where reliable voltage基准ing is critical for system performance and calibration.

Voltage Reference Replacement Considerations

Direct substitutes include LM4050AIM3-2.0/NOPB and LM4050BIM3-2.0/NOPB. Verify pin compatibility and electrical specifications match before substitution. Alternative packages may require PCB layout adjustments.
