Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required package type and lead configuration. Cross-reference datasheet revisions to confirm compliance with current environmental regulations such as RoHS and REACH before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring a wide input voltage range up to 40V and adjustable output voltages. Consider the 3A current capability and 100kHz switching frequency for applications needing moderate power density. Evaluate thermal management requirements due to the TO-263-7 package size and ensure external components support the desired topology.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2586 series of SIMPLE SWITCHER regulators. It is distinct from fixed-output variants like the LM2586SX-5.0/NOPB by offering an adjustable output voltage. The 'S' suffix indicates the surface-mount TO-263-7 package, differentiating it from through-hole options like the LM2586T series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2586 series variants with compatible packages and electrical ratings. Verify that alternative parts support the same boost/flyback/forward topologies and meet the 40V input and 3A output requirements.
