Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix and package type against the manufacturer's latest datasheet to ensure compatibility with thermal management requirements. Confirm that the adjustable output configuration matches the intended circuit design parameters. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the TO-220 mounting style aligns with the PCB layout and heat sinking strategy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-current step-up solution is required with moderate switching frequencies. The TO-220 package facilitates through-hole mounting and direct heatsinking. Consider the 40 V maximum input limit when designing for automotive or industrial environments with potential transients. Evaluate thermal performance based on the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2585 series of SIMPLE SWITCHER regulators from Texas Instruments. The series includes various packages such as TO-263 (SMD) and TO-220 (through-hole). The 'ADJ' suffix indicates adjustable output voltage, while 'NOPB' denotes lead-free and rohs compliant construction. It is distinct from the LM2575 (buck) and LM2596 (buck) series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2585S-ADJ/NOPB serves as a surface-mount equivalent in a TO-263 package. Verify pinout compatibility and thermal characteristics before substitution. Other family members like the LM2586 are buck converters and are not functionally interchangeable.
