Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations like #TG16 or standard tape-and-reel formats may exist. Confirm availability status through authorized distributors, as this component may be subject to limited stock or end-of-life restrictions. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 2.5 V reference with ±0.1% accuracy is required in a small SOT-23-6 package. Consider the 40 ppm/°C temperature coefficient for environmental stability needs. Evaluate the 85 µA quiescent current against battery life constraints. Compare noise specifications if low-frequency drift impacts system signal integrity.

Part Context

This part belongs to the MAX6033 family of ultra-low-power, high-precision voltage references. The family offers various output voltages and accuracy grades, all sharing similar low-power architectures and compact packaging. These devices are designed for applications demanding high stability and minimal power consumption in space-constrained environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6033 series offering different accuracies or voltages. Verify equivalent performance metrics from other manufacturers if sourcing alternatives due to availability issues.
