Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as National Semiconductor is now part of Texas Instruments. Confirm the suffix /NOPB indicates lead-free/RoHS compliance. Check datasheet revisions for any pinout or electrical parameter updates compared to older NS versions. Ensure the TO-263-7 package matches your PCB footprint requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a wide input range. Consider the 5 A current limit and 200 kHz frequency for thermal and EMI design. Compare with LM2588SX variants if reel packaging is preferred over tape-and-reel quantities. Evaluate thermal performance in the TO-263 package for high-load applications.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the SIMPLE SWITCHER family, designed for ease of use in power conversion. Replaces older National Semiconductor parts like LM2588S-5.0. Offers integrated protection features typical of TI's power management ICs. Suitable for replacing legacy components in existing designs requiring robust flyback regulation.
