LM4040QCIM3-2.5/NOPB

Overview

The LM4040QCIM3-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed output of 2.5 V with an initial accuracy of 1%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA.

Feature Summary

AEC-Q100 qualified for automotive reliability standards
Micropower operation suitable for battery-powered applications
Compact SOT-23-3 package for space-constrained designs

Applications

Automotive electronic systems requiring stable voltage references
Portable devices utilizing battery power supplies
Precision measurement instrumentation circuits

Procurement Notes

Verify the AEC-Q100 qualification status and specific operating temperature range against project requirements. Confirm that the SOT-23-3 package dimensions align with PCB layout constraints. Ensure the 1% initial accuracy meets circuit tolerance specifications before finalizing procurement decisions.

Selection Notes

Select this component when automotive-grade reliability is required alongside low power consumption. The 1% accuracy provides sufficient precision for many general-purpose applications. Consider the SOT-23-3 footprint if board space is limited compared to larger through-hole alternatives.

Part Context

This device belongs to the LM4040-N series of precision shunt voltage references. It serves as a reliable reference source for analog-to-digital converters and digital-to-analog converters in industrial and automotive environments where stability and low power are critical design factors.

Replacement Considerations

LM4040QDIM3-2.5/NOPB offers similar automotive qualification but may differ in thermal performance or specific electrical characteristics due to package variations.
