Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required grade and package configuration. Review the latest datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when space constraints require a small SOT23-5 package alongside precise voltage referencing needs. Consider the E-grade specifications if the application tolerates ±0.5% initial accuracy and 30 ppm/°C drift. Evaluate the low power consumption benefits against the requirement for stable operation under varying capacitive loads.
