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

Verify the specific suffix 'PR-G' corresponds to the SOT-89-5 package and RoHS compliance status. Confirm the 'A' designation indicates High Active logic with a pull-down resistor on the CE pin. Ensure the ordering code matches the required 2.80V output specification. Cross-reference the manufacturer's latest datasheet for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement.

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

Select this component for applications requiring a stable 2.80V rail with high current capability up to 700mA. The A-type configuration is suitable for systems where the enable signal is active-high. Consider the low quiescent current for battery-operated devices. Verify that the input voltage remains within the 1.50V to 6.00V range under all operating conditions. Ensure appropriate input and output capacitors are used to maintain stability with low ESR ceramics.

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

This part belongs to the XC6210 series of high-current, high-speed LDO regulators. The series is fabricated using Torex’s proprietary CMOS process. Other variants in the series differ by output voltage, accuracy, and CE pin logic (Types A, B, C, D). The XC6210A28APR-G specifically offers a 2.80V output in a SOT-89-5 package with high-active enable logic.

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

Direct replacements must match the 2.80V output, SOT-89-5 package, and High Active CE logic. Check equivalent parts from other manufacturers for similar current ratings and dropout characteristics. Verify pinout compatibility, particularly the CE pin function and NC pin placement.

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

What is the logic level for the CE pin on the XC6210A series?

The XC6210A series has a High Active CE pin with an internal pull-down resistor. The device is enabled when the CE pin voltage is high and enters standby mode when the CE pin voltage is low.

Does the XC6210A28APR-G require external feedback resistors?

No, the XC6210A28APR-G is a fixed output regulator. The output voltage is internally set to 2.80V and does not require external resistors for voltage adjustment.

What type of output capacitor is recommended for stability?

The device is compatible with low ESR ceramic capacitors. For a 2.80V output, a minimum capacitance of 1.0μF is recommended for the output capacitor (CL) to ensure stability.
