Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm whether the specific variant requires industrial or extended temperature ratings. Ensure the pinout configuration aligns with the target PCB footprint. Check RoHS compliance status if environmental regulations apply. Validate the manufacturer part number against official TI documentation before procurement.

Selection Notes

Select this component when a fixed 1.225V reference with ±0.5% accuracy is required. Consider the SC-70-5 package for space-constrained designs. Evaluate the 150 ppm/°C temperature coefficient against application thermal requirements. Choose this part over adjustable variants if a fixed voltage simplifies the circuit design. Verify the operating current range meets the system's power budget constraints.
