Procurement Notes

Verify the specific suffix 'CIM7X' against the official datasheet to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the required SC-70-5 package dimensions and pinout. Confirm RoHS compliance status through the manufacturer's latest product information page before final procurement.

Selection Notes

Select this component when an adjustable voltage reference is required in space-constrained designs. The SC-70-5 package provides a compact footprint compared to larger alternatives. The 0.5% accuracy and 150 ppm/°C temperature coefficient suit general-purpose precision applications. Consider the 12mA maximum current limit when designing the biasing network for higher load requirements.
