Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the package variant matches the required PCB footprint. Ensure the supplier provides valid traceability documentation. Cross-reference the full part number against the latest datasheet revision to confirm pinout compatibility before integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 40 V is required alongside high output current capabilities. The adjustable output feature allows customization for various load requirements. Consider the thermal performance of the TO-263-7 package for heat dissipation needs. Evaluate the 200 kHz frequency against EMI constraints and inductor size limitations in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2588 series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2587 and LM2596 but offers distinct current ratings and switching frequencies.
