Procurement Notes

Verify the specific package type and tape-and-reel configuration against the official STMicroelectronics datasheet before ordering. Confirm that the suffix 'BDT' corresponds to the required surface-mount packaging variant. Ensure compatibility with existing PCB footprint designs and soldering profiles. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when a fixed 2.5V reference is required with minimal external components. Consider the wide operating current range if the application involves variable load currents. Evaluate the temperature coefficient specifications against the operational environment's thermal profile. Compare dynamic impedance values if load transient response is critical for the specific circuit design.
