Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRMPBF confirms the tape and reel packaging format containing 500 pieces. Ensure the component matches the specified commercial temperature grade (0°C to 70°C) rather than industrial or high-grade variants. Confirm the manufacturer designation as Analog Devices Inc. to avoid counterfeit parts.

Voltage Reference Selection Notes

Select this part when a compact SOT-23 footprint is required alongside precise voltage referencing. It is suitable for applications needing low quiescent current and stable performance under varying load conditions. Consider the 0.9V dropout voltage when designing power rails to ensure sufficient headroom for regulation.
