Voltage Reference Procurement Notes

Verify the specific suffix codes against official Texas Instruments documentation to confirm exact electrical tolerances and automotive qualification status. Ensure compatibility with existing PCB footprints and thermal management requirements before integration. Cross-reference ordering information with authorized distributors to avoid counterfeit components and confirm RoHS compliance status.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with ±0.1% accuracy is required in a small form factor. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum shunt current capability against load requirements. Compare against other LM4050 variants if different output voltages or tighter tolerances are necessary for the specific application design.

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The 'A' suffix typically denotes higher precision compared to standard grades. The 'M3' indicates the SOT-23-3 package type, while 'NOPB' signifies lead-free and rohs-compliant construction without blue polymer coating.

Voltage Reference Replacement Considerations

LM4050AIM3-2.5/NOPB is listed as Not Recommended for New Design (NRND). Official documentation suggests LM4050AIM3-2.5/NOPB as an alternate, though availability varies. Verify functional equivalence with LM4050CEM3-2.5/NOPB or LM4050QAEM3-2.5/NOPB based on required accuracy and qualification levels.
