Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'G' indicates lead-free and halogen-free compliance per RoHS standards. Confirm the package type matches the TO-220 physical dimensions required for your thermal management design. Ensure the ordering part number exactly matches LM2576TV-015G to guarantee the specific 1.5 V output voltage variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed low-voltage output is required without external feedback resistors. It is suitable for designs prioritizing simplicity over adjustable voltage ranges. Consider the thermal dissipation requirements given the 3 A current capability and the specific input-to-output voltage differential in your application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of monolithic integrated step-down switching regulators. The family offers various fixed output voltages to simplify design. The TV suffix denotes the TO-220 package style, which provides robust mechanical stability and heat dissipation capabilities compared to smaller surface-mount alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes include other LM2576 variants with different output voltages if the voltage level can be adjusted externally, though the -015G is fixed. Cross-referencing with equivalent parts from other manufacturers requires verifying pinout compatibility and ensuring similar thermal and electrical ratings are met.
