Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for the NRND (Not Recommended for New Designs) lifecycle status before finalizing procurement decisions. Ensure packaging specifications match production requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring wide input voltage ranges up to 95 V. Consider the WSON-8 package constraints for thermal management. Evaluate the 350 mA output capability against load requirements. Verify that the selected switching frequency aligns with passive component size and efficiency targets.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5008A family of high-voltage buck regulators. It shares functional similarities with the LM5009 but offers higher output current capacity. The ASD suffix indicates the specific WSON-8 package variant. It serves as a power management IC for converting higher bus voltages to lower logic or sensor levels.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM5008AMM/NOPB if an MSOP package is required instead of WSON-8. Verify compatibility with LM5009 variants if lower current is acceptable. Ensure substitute parts maintain the same high-voltage input rating and synchronous topology.
