Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS standards. Confirm the T suffix corresponds to the TO-220-7 package variant. Ensure the ADJ designation matches the required adjustable output configuration rather than fixed voltage options. Cross-reference datasheet revisions for any pinout or electrical parameter updates before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing boost or flyback topologies requiring high input voltage tolerance up to 40V. The adjustable output allows flexibility for various system rail requirements. Consider the TO-220-7 package for through-hole mounting applications where thermal dissipation is critical. Evaluate external inductor and capacitor values based on the desired output voltage and load current specifications.
