Voltage Reference Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with design requirements. Confirm that the component meets all necessary environmental and regulatory standards for the intended application environment before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with 0.5% initial accuracy is required. Ensure the operating temperature range up to 85°C aligns with system constraints. Consider the SOT-23-3 package size for layout compatibility and verify power dissipation limits under maximum load conditions.

Voltage Reference Part Context

This part belongs to the LM4050-N series of precision shunt voltage references from Texas Instruments. It shares architectural similarities with other members of the family but differs in output voltage, accuracy grades, and thermal specifications. The NOPB suffix indicates lead-free construction compliant with RoHS directives.

Voltage Reference Replacement Considerations

LM4050CEM3-2.5/NOPB offers similar electrical characteristics with extended temperature range capabilities. LM4040CIM3-2.5/NOPB provides comparable functionality but with different temperature coefficient specifications. Verify pinout and thermal performance before substitution.
