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

Verify the specific ordering suffix '1R-G' corresponds to the LGA-4B01 package type and reel quantity as defined in the official datasheet. Confirm that the 'H' designation indicates the inclusion of the inrush current protection circuit. Ensure compatibility with the required ceramic input and output capacitors for stable operation.

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

Select this component when a compact footprint is required alongside precise voltage regulation. The H-type variant is necessary if inrush current limiting during startup is a system requirement. Verify that the load current does not exceed the 300mA maximum rating and that the input voltage remains within the specified operational range.

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

This part belongs to the XC6229 series of ultra-small high-speed LDO regulators. The series is characterized by high accuracy, low power consumption, and compatibility with low ESR ceramic capacitors. The 'H' type specifically integrates inrush current protection, distinguishing it from the standard 'D' type which lacks this feature.

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

XC6229H35B1R-G is a direct replacement for other XC6229H35xxR-G variants with different accuracy codes (e.g., B vs 1) if the ±1% tolerance is acceptable. Cross-series replacements require verification of pinout compatibility and electrical parameter alignment.
