LM4040D50IDBZT

Overview

The LM4040D50IDBZT 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 ±1%. The device operates within an extended temperature range from -40°C to +125°C and features a maximum temperature coefficient of 150ppm/°C. It utilizes a SOT-23-3 surface-mount package and requires a typical minimum cathode current of 45μA for stable operation.

Feature Summary

• Provides a fixed 5V reference output with tight manufacturing tolerances.
• Operates reliably across an extended industrial temperature range.
• Designed for low power consumption suitable for portable applications.
• Maintains stability with all capacitive loads without requiring external capacitors.

Applications

• Data-acquisition systems
• Energy infrastructure monitoring
• Analog input modules
• Field transmitters

Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 package and tape-and-reel delivery format. Confirm that the 'D' grade designation aligns with the required ±1% accuracy and 150ppm/°C temperature coefficient specifications for your design. Ensure the component meets RoHS compliance requirements for your region.

Selection Notes

Select this component when a fixed 5V reference is needed in space-constrained designs. The D-grade specification offers a balance between cost and performance, suitable for applications where ±1% accuracy is sufficient. Consider the extended temperature rating if the operating environment exceeds standard industrial limits.
