Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TJ' corresponds to the TO-263 package variant when sourcing. Confirm that the '-5.0' designation indicates the fixed 5V output version rather than the adjustable configuration. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required with up to 3A load current. It is suitable for applications where input voltages vary significantly between 4.5V and 42V. Consider the thermal performance of the TO-263 package for heat dissipation requirements. Evaluate the 500kHz switching frequency against EMI constraints and inductor size limitations in the target application.
