Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the component status carefully, as this specific part number is listed as obsolete by major distributors. Confirm availability of alternative packages or updated series revisions if current stock is unavailable. Ensure the replacement maintains the same TO-263 footprint and electrical specifications to fit existing designs without modification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from high-voltage inputs up to 60V in automotive contexts. The TO-263 package offers thermal performance suitable for 1A loads. Consider the obsolete status and plan for long-term supply chain risks. Verify that the fixed 5V setting meets the load requirements without needing external adjustment resistors.
