Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' confirms the through-hole PDIP-8 package variant. Confirm the '5.0' designation indicates the fixed 5V output version rather than the adjustable model. Ensure compatibility with standard DIP footprints during PCB layout planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, single-output buck converter is needed for moderate current loads under high input voltage conditions. The PDIP package suits prototyping or applications where surface mount assembly is not required. Compare against SOIC variants if board space constraints exist.
