Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix 'N33' confirms the fixed 3.3V output variant. Ensure the package marking matches the SOT363 (SC-88) outline. Confirm RoHS compliance status through official ST documentation prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a single-cell lithium-ion or lithium-polymer battery source. The integrated design minimizes board space compared to discrete solutions. Consider the 3A current limit for load requirements exceeding typical low-power regulators.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the L6983 family of synchronous step-down converters. It shares architectural similarities with other models in the series but differs in output configuration. The 'QTR' suffix indicates tape-and-reel packaging suitable for automated surface-mount assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other STMicroelectronics synchronous buck converters with similar input ranges and current capabilities. Verify pin compatibility and thermal performance before swapping. Cross-reference datasheets for equivalent switching frequencies and protection features.
