If your rail target is one of those two values, you save two resistors and one feedback-node noise source. The 300 mA ceiling suits low-power MCU cores, RF transceivers, or sensor bias rails. The synchronous rectifier improves efficiency at light loads compared to a diode-based buck, which is relevant for battery-operated gear where every milliamp of quiescent current counts.
Buyers need to find a reliable source with stock to avoid production delays.
Design engineers must validate PCB layout and ensure correct connections.
Sourcing flexibility and cost optimization require known compatible substitutes.
Brokers and buyers need lifecycle status to plan long-term availability.
Budgeting and BOM costing rely on accurate pricing information.
Design engineers need to set the correct output using external resistors.
