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

Verify the specific suffix 'PR-G' corresponds to the SOT-89-5 package configuration as defined in the official ordering information. Confirm that the 'C' type designation aligns with the required CE pin pull-down resistor functionality and the specified operating temperature range. Ensure compatibility with ceramic capacitors for phase compensation as detailed in the application notes.

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

Select this component for applications requiring a fixed 2.05V rail with high current capability up to 700mA. The C-type variant includes a pull-down resistor on the CE pin, ensuring a defined standby state if the control pin is left open. Verify that the required output capacitance meets the phase compensation guidelines for the 2.05V output setting to maintain stability.

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

Direct substitutes within the same series include other XC6227 variants with different output voltages or package types, such as XC6227C20BMR-G (SOT-25) or XC6227C20BER-G (USP-6C). Cross-series replacements require verification of pinout compatibility, current ratings, and electrical specifications against the original design constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the reverse current protection circuit?

The reverse current protection circuit prohibits current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage, preventing damage from external power sources connected to the output.

How does the CE pin behave in the C-type version?

The C-type version includes an internal pull-down resistor on the CE pin. If the CE pin is left open, the IC enters the stand-by state automatically.

What type of output capacitor is recommended?

Low ESR ceramic capacitors are recommended. For the 2.05V output, a capacitance of 6.8μF or higher is typically required for stable phase compensation.
