Procurement Notes
Verify the specific suffix 'DBZR' corresponds to the SOT-23-3 surface-mount package and tape-and-reel shipping configuration. Confirm the 'I' grade designation aligns with the required industrial temperature range of -40°C to 85°C. Ensure the 'A' grade matches the 0.1% initial accuracy specification for your circuit requirements.
Selection Notes
Select this component when a 10V reference with 0.1% accuracy is needed in a compact SOT-23-3 footprint. It is suitable for designs requiring stability with capacitive loads without additional output capacitors. Consider the 45μA minimum operating current for low-power battery applications.
