Voltage Reference Procurement Notes

Verify the specific suffix 'DMF' against official Texas Instruments documentation to confirm pinout and thermal characteristics match your design requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside moderate precision (±0.2%) and low quiescent current. It is suitable for applications where space constraints limit the use of larger packages but still demand better stability than standard shunt references. Consider the shutdown feature if system power efficiency is critical.
