Voltage Reference Procurement Notes

Verify the specific suffix 'X' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact electrical tolerances required for the design. Cross-reference the manufacturer's latest documentation to confirm active status and any potential obsolescence notices before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a stable 2.5V reference is needed in space-constrained designs requiring minimal quiescent current. The SC-70-3 package offers a compact footprint suitable for dense PCB layouts. Consider the ±0.5% initial accuracy for applications demanding tighter voltage regulation without external trimming.

Voltage Reference Part Context

This part belongs to the LM4431 family of micropower shunt references. It serves as a cost-effective alternative to more complex voltage reference solutions. The series is widely used in consumer electronics and industrial controls where size and power efficiency are critical constraints.
