Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status as per official documentation. Confirm availability status, as distribution channels may list this component as End-of-Life or Not Recommended for New Designs depending on the region and date. Ensure the ordering part number matches the exact tolerance and package variant required for your design.

Voltage Reference Selection Notes

Select this component when a 2.5 V shunt reference with 0.1% initial accuracy is required in a small SOT-23-3 package. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15 mA maximum shunt current capability meets the circuit's power dissipation requirements. Compare against other LM4050 variants if different output voltages or accuracies are needed.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'A' grade denotes tighter initial accuracy specifications compared to lower grades. The 'M3' indicates the SOT-23-3 package type, and 'X' typically signifies tape-and-reel packaging configuration.

Voltage Reference Replacement Considerations

Check for direct substitutes within the LM4050 family with matching voltage and accuracy. Verify pinout compatibility with SOT-23-3 packages. Consult Texas Instruments documentation for any recommended alternate parts if this specific suffix is discontinued.
