Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance. Confirm the TO-220-5 package matches your PCB footprint requirements. Ensure the 60V maximum input rating aligns with your system's supply voltage. Check that the 3A continuous current capacity meets load demands. Validate the operating temperature range covers your environmental conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when input voltages exceed standard regulator limits but remain below 60V. Choose the adjustable version if specific output voltages are required beyond fixed options. Consider the TO-220-5 package for through-hole assembly needs. Evaluate thermal management requirements given the 3A output capability and lack of synchronous rectification.
