Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '3D' confirms the 3.35 V output voltage setting, as this variant differs from other fixed-voltage options in the XC9285 series. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the SOT-25-5 footprint matches the target PCB layout requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.35 V output is required rather than standard 3.3 V variants. The low quiescent current makes it suitable for battery-operated applications where standby power consumption is critical. Verify that the 1 A output current capability meets the peak load demands of the target circuit design.
