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 system requirements, as discharge functionality is only available in the 'D' suffix version. Ensure compliance with RoHS directives and verify moisture sensitivity level 1 handling procedures during assembly.

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

Select this component for applications requiring minimal ground current and high voltage precision in compact form factors. The X2-DFN1010-4 package offers thermal resistance suitable for moderate power dissipation up to 315mW. Consider the enable pin requirement if dynamic power control is necessary, noting that floating EN pins are not permitted for proper operation.
