LM4040CEM3-5.0/NOPB

Overview

The LM4040CEM3-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 5 V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of ±0.5%. The device exhibits a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 15 mA. Packaged in a compact SOT-23 form factor with three pins, it measures 0.93 mm in height.

Feature Summary

Micropower shunt topology for low current consumption
Fixed 5 V precision output reference
Compact SOT-23 surface-mount package

Applications

Portable battery-powered instrumentation
Data acquisition systems
Handheld meters

Procurement Notes

Verify the specific suffix 'CEM3' against official documentation to confirm the exact accuracy grade and temperature coefficient, as variations exist within the LM4040 family. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the datasheet revision date to ensure alignment with current design specifications.

Selection Notes

Select this component when a fixed 5 V reference is required in space-constrained designs utilizing SOT-23 packages. It is suitable for applications demanding moderate precision (±0.5%) and operation across standard industrial temperatures. Consider the 15 mA maximum shunt current limit when designing the biasing resistor network.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040CEM3-5.0/NOPB specifically targets cost-sensitive applications requiring reliable performance in small footprints, serving as a stable reference for analog-to-digital converters and other precision circuits.

Replacement Considerations

Official documentation lists the LM4040CEM3-5.0/NOPB as NRND (Not Recommended for New Designs). Designers should evaluate alternative components from the manufacturer's portfolio that offer similar electrical characteristics and packaging to ensure long-term supply availability.
