Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '013TR' corresponds to the reel packaging format when ordering. Confirm that the 8-SOIC package dimensions align with your PCB footprint requirements. Ensure compatibility with the 250kHz switching frequency regarding external inductor and capacitor selection. Validate that the 2A current limit meets the peak load demands of the target application circuit.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a non-synchronous buck converter with high input voltage tolerance up to 36V. It is suitable for applications where a fixed 250kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 2A switch limit when determining maximum continuous load current based on thermal conditions and duty cycle constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the L5972D series of step-down regulators. It shares core specifications with the tube-packaged L5972D but differs in shipping configuration. The series is designed for general-purpose power management, offering a balance of performance and simplicity through integrated protection features and minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

L5972D (tube package) offers identical electrical characteristics with different packaging. A5972D013TR is an automotive-grade variant with AEC-Q100 qualification but reduced output current capability.
