Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix FS4 corresponds to the X2-DFN1010-4 package type when sourcing components. Confirm that the non-discharge variant matches the system's shutdown requirements, as discharge versions carry a distinct D suffix. Ensure compliance with RoHS directives and moisture sensitivity level 1 ratings during storage and handling procedures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring minimal ground current draw while maintaining stable regulation under varying loads. The fixed 3.0V output eliminates external resistor networks, simplifying PCB layout. Verify that the input voltage remains above the minimum threshold to ensure proper operation and check thermal dissipation limits based on the expected junction-to-ambient resistance.
