Overview
The LM4040QBIM3X2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 2.5 V with an initial accuracy of ±0.1%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C and supports a maximum cathode current of 15 mA. The device exhibits a low temperature coefficient of 40 ppm/°C and meets AEC-Q100 automotive qualification standards.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in demanding environments.
- High precision voltage regulation achieved through tight initial accuracy tolerances and low thermal drift characteristics.
- Micropower operation design enables efficient energy usage suitable for battery-powered and space-constrained applications.
Applications
- Automotive electronic systems requiring qualified voltage references
- Precision analog-to-digital converter (ADC) reference inputs
- Battery-operated instrumentation circuits
Procurement Notes
Verify the complete part number including the Q prefix for automotive grade and IM3X suffix for tape-and-reel packaging. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation for automotive components. Cross-reference datasheet revisions to match specific manufacturing lot requirements.
Selection Notes
Select this component when automotive qualification is mandatory alongside high precision requirements. Compare against non-automotive variants if environmental stress testing is not required. Ensure the SOT-23 footprint aligns with existing PCB layout constraints and verify that the 15 mA current limit suffices for the load conditions.
Part Context
This device belongs to the LM4040 series of micropower shunt voltage references. It shares the core architecture with other LM4040 variants but distinguishes itself through automotive certification and specific tolerance grades. The series offers various fixed voltage options and package types to support diverse power management needs.
Replacement Considerations
LM4040BIM3X-2.5/NOPB serves as a non-automotive equivalent with identical electrical specifications but lacks AEC-Q100 certification. Verify if automotive qualification is strictly necessary before substituting.
