Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 'T' designation corresponds to the TO-220 through-hole package variant rather than surface-mount alternatives. Ensure the 'ADJ' suffix matches the requirement for an adjustable output voltage configuration instead of fixed voltage options. Cross-reference the datasheet revision history for any updates regarding thermal performance or pinout definitions before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-current step-up solution is required with a wide input voltage span up to 40V. The adjustable output feature allows flexibility for various load requirements within the 1.23V to 60V range. Consider the TO-220 package for applications where through-hole mounting and robust heat dissipation are prioritized over compact surface-mount footprints. Evaluate the 100kHz switching frequency against electromagnetic interference constraints in the target design environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2586 series of SIMPLE SWITCHER regulators, which are designed for high-efficiency power conversion. The series includes both fixed and adjustable output variants. The LM2586T-ADJ/NOPB specifically represents the adjustable version in a through-hole package, distinguishing it from surface-mount counterparts like the LM2586S-ADJ. It serves as a core component for designing boost and flyback converters in industrial and commercial electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2586T-ADJ/NOPB is a direct replacement for the older LM2586T-ADJ part number, with the NOPB suffix indicating enhanced environmental compliance. Designers should verify that alternative components match the 7A peak current capability and the 40V maximum input voltage limit. Package compatibility must be confirmed if substituting with other manufacturers' equivalents.
