Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing from distributors. Confirm the B-grade designation matches the required ±0.06% accuracy and 7ppm/°C drift specifications for your design. Ensure the commercial temperature range (0°C to 70°C) meets your operational environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 3V reference with ±0.06% initial accuracy is required. It is suitable for applications needing low quiescent current alongside moderate load drive capabilities. Consider the SOIC-8 package constraints and ensure adequate board layout practices are followed to minimize mechanical stress effects on long-term stability.

Voltage Reference Part Context

This part belongs to the LT1461 family of bandgap references, which utilize advanced curvature compensation and trimmed thin-film resistors. The family offers various voltage options and accuracy grades, ranging from standard to high precision, all sharing similar low dropout characteristics and micropower profiles designed for portable and battery-operated systems.
