Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against the manufacturer datasheet to confirm the fixed 5.0 V output variant. Ensure the SO-PowerPAD-8 package matches your PCB footprint requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the specific ordering number with official TI documentation to avoid confusion with adjustable or other fixed-voltage versions within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a wide input range up to 42 V. The 500 mA current rating suits low-power applications where space efficiency is critical due to the compact 8-SO PowerPAD package. Consider the 500 kHz switching frequency for balancing component size and electromagnetic interference. Verify thermal performance requirements given the high junction temperature capability.
