Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TV' indicates the TO-220-5 curved lead package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer declaration. Ensure the supplier provides official datasheets matching the LM2575 series specifications. Cross-reference the part number with onsemi's official ordering information to avoid confusion with surface-mount or fixed-voltage variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole solution is required for high-current buck applications. The adjustable output range suits designs needing non-standard voltages. Consider the 52kHz switching frequency for EMI constraints. Evaluate thermal dissipation requirements due to the TO-220 package's power handling characteristics. Compare against fixed-output versions if standard voltages suffice.
