LM4040QCIM3X2.5/NOPB

Overview

The LM4040QCIM3X2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a SOT-23-3 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 15 mA and requires a minimum operating current of 60 µA. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

AEC-Q100 qualified for automotive reliability standards
Micropower operation with low minimum current consumption
Wide operating temperature range suitable for harsh environments

Applications

Automotive electronic systems requiring precise voltage references
Portable battery-powered equipment due to low power consumption
Data acquisition systems needing stable reference voltages

Procurement Notes

Verify the specific suffix 'X' indicates the tape-and-reel packaging format as per manufacturer documentation. Confirm that the AEC-Q100 qualification aligns with your project's automotive grade requirements. Ensure the 1% accuracy specification meets your circuit tolerance needs. Check for any lead-free or RoHS compliance statements in the official datasheet before finalizing procurement.

Selection Notes

Select this component when automotive qualification is mandatory alongside low-power constraints. The SOT-23-3 package offers space efficiency for compact designs. Consider the 150 ppm/°C temperature coefficient against stricter precision requirements. Compare with non-automotive grades if cost sensitivity outweighs the need for AEC-Q100 certification.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references by Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'Q' prefix denotes automotive qualification, while 'CIM3' specifies the SOT-23 package and commercial/extended temperature range variants.
