Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix 'NOPB' confirms lead-free status and RoHS compliance as per manufacturer specifications. Ensure the 'X' designation matches the required tape-and-reel packaging format rather than tube distribution. Confirm the specific variant aligns with the intended thermal management strategy for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.3V output is required alongside high input voltage tolerance up to 60V. The TO-263 package offers a balance between thermal dissipation capabilities and surface-mount convenience. Consider the 52kHz switching frequency for appropriate inductor selection and EMI filtering requirements within the system architecture.
