Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as regulatory status may vary by production batch. Ensure the component matches the required DFN-6 footprint and pinout for your PCB design before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from low-voltage sources between 0.9 V and 5.5 V. It is suitable for designs prioritizing minimal standby current and small board area over high output current capabilities. Consider alternative regulators if output currents exceeding 60 mA are necessary or if adjustable output voltages are required.
