Voltage Reference Procurement Notes
Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lots. Validate package markings against official datasheet specifications to prevent counterfeit substitution during procurement processes.
Voltage Reference Selection Notes
Select this component when a 2.5 V reference with moderate precision is required in space-constrained designs. Consider the SOT-23-3 package for board area optimization. Evaluate thermal management requirements given the operating temperature limits and power dissipation characteristics inherent to shunt reference topologies.
Voltage Reference Part Context
This part belongs to the LM4050-N series of micropower shunt voltage references. It shares functional similarities with other variants in the family but differs in output voltage and accuracy grades. The NOPB suffix indicates lead-free construction compliant with environmental directives.
