LM4040DIM3-3.0+T

Overview

The LM4040DIM3-3.0+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 3.000V with an initial accuracy of 1.0% and a maximum temperature coefficient of 150ppm/°C. The device operates within a wide current range from 60μA to 15mA and is housed in a subminiature 3-pin SOT23 surface-mount package. It is guaranteed for operation over the industrial temperature range of -40°C to +85°C.

Feature Summary

• Laser-trimmed resistors ensure precise initial accuracy across multiple grades.
• Low dynamic impedance maintains stable reverse breakdown voltage accuracy over a wide operating current range.
• Internal design eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load.

Applications

• Portable, battery-powered equipment
• Notebook computers
• Cell phones
• Industrial process controls

Procurement Notes

Verify the specific suffix '+T' corresponds to tape and reel packaging as defined in the official ordering information table. Confirm that the 'D' grade designation aligns with the required 1.0% initial accuracy and 150ppm/°C temperature coefficient specifications for your application. Ensure the component meets RoHS compliance requirements indicated by the '+' symbol in the part number.

Selection Notes

Select this component when a fixed 3.000V reference is needed in space-constrained designs utilizing the SOT23-3 package. The D-grade specification offers a balance of cost and performance for applications tolerating 1.0% initial accuracy. Consider the 150ppm/°C temperature coefficient when calculating total error budgets over the -40°C to +85°C operating range.

Part Context

This component belongs to the LM4040 family of micropower shunt voltage references. The family includes variants with different output voltages (2.048V, 2.500V, 3.3V, 4.096V, 5.000V) and accuracy grades (A, B, C, D). The DIM3 suffix specifically denotes the Industrial temperature range (-40°C to +85°C), SOT23 package, and 1.0% accuracy grade.

Replacement Considerations

LM4040CIM3-3.0+T offers 0.5% accuracy with the same package and temperature range. LM4040BIM3-3.0+T provides 0.2% accuracy. For extended temperature ranges, consider LM4040DEM3-3.0+T which shares the 1.0% accuracy but operates up to +125°C.
