Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free status and RoHS compliance as per manufacturer specifications. Ensure the ordering part number matches the required TO-263-5 surface mount package configuration. Confirm that the fixed 12 V output variant aligns with system voltage requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a wide input range. The TO-263-5 package offers thermal performance advantages over smaller packages. Consider the 150 kHz switching frequency for balancing component size and efficiency against noise sensitivity in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 series of SIMPLE SWITCHER regulators, designed for low component count applications. It represents the surface-mount variant (S) within the family, distinct from through-hole versions. The NOPB suffix indicates it is manufactured without lead-based materials, adhering to environmental standards.
