Voltage Regulators - DC DC Switching Regulators Procurement Notes

This component is officially discontinued and no longer recommended for new designs. Verification of end-of-life status is required before integration into any project. Availability is limited to existing stock or secondary markets, and long-term supply cannot be guaranteed. Designers should consult official documentation for final discontinuation dates and transition recommendations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part only for legacy system maintenance or repair where pin compatibility is critical. The fixed 1.2V output limits flexibility compared to adjustable variants. Consider the 1.5A current limit and 5.5V maximum input when evaluating load requirements. Verify thermal performance in the USP-C-EP-6 package for your specific application environment.
