LM4040B25QFTA

Overview

The LM4040B25QFTA is an automotive-compliant precision micropower shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 2.5V with an initial tolerance of ±0.2% at +25°C. The device operates within a wide current range of 60µA to 15mA and maintains stability over an extended temperature range from -40°C to +125°C. It features a low maximum temperature coefficient of 100 ppm/°C and utilizes a compact SOT-23 surface-mount package.

Feature Summary

Automotive compliant design suitable for specific change control requirements
High precision B-grade initial tolerance of ±0.2%
Capable of maintaining excellent stability with capacitive loads

Applications

Automotive reference voltages
Automotive data acquisition systems

Procurement Notes

Verify the component matches the exact part number LM4040B25QFTA, ensuring the 'Q' suffix indicates automotive compliance and the 'B' grade specifies the required 0.2% tolerance. Confirm that the manufacturer is Diodes Incorporated and check datasheet revision DS36989 Rev. 3-2 for accurate electrical specifications before finalizing procurement.

Selection Notes

Select this component when high accuracy is required in space-constrained automotive environments. The B-grade tolerance ensures tight voltage regulation, while the wide operating current range allows flexibility in circuit design. Ensure the application supports the SOT-23 package dimensions and thermal characteristics specified in the datasheet.

Part Context

This device belongs to the LM4040Q family of bandgap circuits designed for automotive applications. It serves as a pin-for-pin compatible alternative to industry standard LM4040 references but includes AEC-Q100 qualification and PPAP capability. The family offers various voltage options and tolerance grades to suit different precision requirements.
