Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 'N' designation corresponds to the MDIP package variant rather than surface-mount options. Cross-reference the full part number against official distributor catalogs to ensure correct pinout alignment for through-hole mounting.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required without external programming resistors. Ensure the application input voltage remains within the 8V to 40V operational window. Verify that the 500mA load current does not exceed the device's thermal limits given the chosen ambient conditions and board copper area.
