Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' or 'C' against the required datasheet revision, as these may indicate different internal revisions or packaging variants. Confirm the SO-8 package dimensions match the PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the RoHS compliance status with current regulatory standards for the target market.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output at 2 A is required from a wide input voltage bus. The low quiescent current makes it suitable for battery-operated applications where standby power consumption is critical. The integrated synchronous rectification improves efficiency compared to non-synchronous alternatives. Consider thermal management requirements given the high output current capability in a small SO-8 package.
