Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture barrier compliance prior to assembly. Cross-reference datasheet specifications against design requirements to ensure compatibility with existing system architectures and thermal constraints.

Selection Notes

Select this component for applications requiring high precision and minimal space consumption. The SOT-323 package suits space-constrained designs. Evaluate the trade-off between the 35ppm/°C temperature coefficient and the specific accuracy needs. Ensure the circuit design accommodates the 15mA maximum output current capability while maintaining low quiescent power consumption.
