LM4040AIM3-5.0/NOPB

Overview

The LM4040AIM3-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed 5V output. It features an initial accuracy of 0.1% and a temperature coefficient of 100 ppm/°C. The device operates within a current range of 60 µA to 15 mA and supports an operating temperature range from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount case with dimensions of 2.92mm x 2.92mm x 0.93mm, it is designed for precision applications requiring low power consumption.

Feature Summary

• Provides stable 5V reference voltage with high initial accuracy
• Micropower operation suitable for battery-powered systems
• Compact SOT-23-3 package for space-constrained designs

Applications

• Portable instrumentation
• Battery-powered measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'AIM3' corresponds to the 0.1% accuracy grade and 100 ppm/°C temperature coefficient. Confirm the '/NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering part number matches the required tolerance and thermal performance specifications for your design.

Selection Notes

Select this component when a 5V reference with 0.1% initial accuracy is required. It is suitable for applications needing low quiescent current around 60 µA. Consider the 100 ppm/°C drift if operating across wide temperature ranges. Verify that the SOT-23-3 package fits the PCB layout constraints.

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 'AI' suffix typically denotes the 0.1% accuracy class, while 'M3' specifies the SOT-23-3 package type. The NOPB suffix confirms environmental compliance.

Replacement Considerations

LM4040AIM3-5.0/NOPB is the direct equivalent. LM4040AIM3X-5.0/NOPB is the tape-and-reel version. LM4040BIM3-5.0/NOPB offers 0.2% accuracy. LM4040CIM3-5.0/NOPB provides 0.5% accuracy.
