LM4040CEM3X-3.0/NOPB

Overview

The LM4040CEM3X-3.0/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 3.0 V in an SOT-23 package. It offers an initial accuracy of 0.5% and a temperature coefficient of 150 ppm/°C. The device operates with a maximum shunt current of 15 mA across a temperature range of -40°C to +85°C.

Feature Summary

Provides stable reference voltage via shunt topology
Designed for low power consumption applications
Ensures high precision through tight initial accuracy tolerance

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring stable references
Microprocessor supply monitoring circuits

Procurement Notes

Verify the specific suffix 'CEM3X' matches the required accuracy grade and packaging variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the operating temperature range aligns with system requirements before procurement.

Selection Notes

Select this component when a fixed 3.0 V reference is needed in a compact SOT-23 form factor. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 0.5% initial accuracy against circuit sensitivity needs.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It serves as a cost-effective solution for applications requiring moderate precision and low current consumption in small surface-mount packages.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify if upgraded accuracy grades or different output voltages are available from the manufacturer.
