Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and functional equivalence. Ensure the component meets required environmental standards such as RoHS compliance before integration. Cross-reference datasheet revisions to validate parameter consistency. Confirm package integrity and moisture sensitivity levels upon receipt.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a fixed 5 V output with up to 5 A capacity. It is suitable for systems operating between 4 V and 40 V input. Consider the TO-263-5 package for surface-mount implementations. Evaluate thermal management requirements due to the power dissipation characteristics of the integrated switch at higher currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2587 series of SIMPLE SWITCHER regulators. The series includes variants with different fixed output voltages (3.3 V, 12 V) and adjustable versions. The 'S' suffix indicates the TO-263-5 surface-mount package, while '/NOPB' denotes lead-free and halogen-free construction compliant with environmental directives.
