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

Verify the specific package type USPQ-4B03 and the extended temperature rating associated with the 'T' designator. Confirm that the CE pin logic matches system requirements, as this variant includes internal pull-down resistance. Ensure ordering suffixes align with RoHS compliance and reel quantities specified by the manufacturer.

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

Select this component for applications requiring fast transient response and low quiescent current. The inclusion of inrush current protection makes it suitable for systems sensitive to power-up spikes. Verify that the required output voltage of 3.4V fits the design constraints and that the operating temperature range extends to 105°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6223 series of high-speed LDO regulators. The series is characterized by high accuracy, low noise, and high ripple rejection. The 'N' designation indicates the presence of inrush current protection and CE pin pull-down functionality, while the 'T' suffix denotes compliance with an extended operating temperature range up to 105°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same series include XC6223H34B9R-G, which shares similar protection features but may differ in temperature rating or CE pin configuration. Cross-series replacements require verification of pin compatibility and electrical parameters.
