Voltage Regulators - DC DC Switching Regulators Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of final availability through authorized distributors is required before design finalization. Confirm end-of-life status and last-time-buy dates via official Skyworks documentation to ensure supply chain stability for production runs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part only if a fixed 3.3V boost output within a 1.8V to 3.3V input range is required. The SOT-23-6 package limits thermal dissipation; verify that the 100mA load does not exceed thermal constraints. Ensure the application tolerates the discontinuation status and can source remaining inventory or qualified substitutes.
