Voltage Reference Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest documentation to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage to the sensitive internal circuitry.

Voltage Reference Selection Notes

Select this component when a 5 V reference with ±0.5% accuracy is required in a small SOT-23-3 package. It is appropriate for applications demanding low quiescent current and wide operating temperature ranges. Consider alternative accuracy grades if tighter tolerances than ±0.5% are necessary for the specific system performance goals.
