Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations such as '+T' or 'TR' may indicate specific tape-and-reel packaging configurations or compliance certifications. Confirm availability status directly with authorized distributors, as supply chain fluctuations can affect lead times. Ensure the ordering part number matches the required output voltage and accuracy grade specified in the design requirements before procurement.

Selection Notes

Select this component when a fixed 3.3V reference with high precision is required in a minimal footprint. The 0.2% initial accuracy and 30ppm/°C temperature coefficient make it suitable for applications demanding stable performance over varying thermal conditions. Consider the 1mA output capability and 125µA supply current to ensure compatibility with downstream circuit load requirements and power budget constraints.
