Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'D-TR' against official datasheets to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance documentation is available from the manufacturer. Check lifecycle status as some sources indicate manufacturing discontinuation; validate current availability directly with authorized distributors or Nisshinbo Micro Devices Inc. before procurement planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck converter with adjustable output is required. Ensure input voltage range matches the application source. Verify that the 800mA output capability meets load demands. Consider the UFDFN package size constraints and thermal requirements for the PCB layout. Compare against newer series like NC2650 if ultra-low quiescent current is a primary design driver.
