LM4040CEM3-5.0

Overview

The LM4040CEM3-5.0 is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5 V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 150 PPM/C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40 C to +85 C and is housed in a SOT-23 surface-mount package.

Feature Summary

• Provides stable fixed output voltage suitable for precision applications
• Designed for space-constrained designs using compact SOT-23 packaging
• Operates reliably across the industrial temperature range

Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition systems needing stable reference voltages

Procurement Notes

Verify component status as NRND (Not Recommended for New Designs) before procurement. Confirm availability of alternate part numbers such as LM4040CEM3-5.0/NO. Ensure sourcing from authorized distributors to guarantee authenticity and traceability for critical design implementations.

Selection Notes

Select this component when a 5 V reference with 0.5% accuracy is required in a small footprint. Consider the 150 PPM/C temperature coefficient against application thermal stability needs. Evaluate the 15 mA maximum shunt current capability against load requirements and ensure compatibility with SOT-23 layout constraints.

Part Context

Part of the LM4040 family of micropower shunt voltage references. This specific variant offers 5 V output with standard industrial grade performance metrics. It serves as a cost-effective solution for general-purpose voltage referencing where ultra-high precision is not mandatory.

Replacement Considerations

Official alternate designation is LM4040CEM3-5.0/NO. Verify pinout and electrical specifications match before substitution.
