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

Verify the specific package type SOT-25 and the A-series logic configuration (CE High Active with pull-down resistor) against system requirements. Confirm that the 4.1V output voltage aligns with the target load specifications. Ensure compliance with EU RoHS and Halogen/Antimony-free standards as indicated by the -G suffix. Check absolute maximum ratings regarding input voltage and power dissipation limits during thermal analysis.

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

Select this component when a fixed 4.1V rail is required with high current capability up to 700mA. The A-series designation indicates active-high enable logic with an internal pull-down resistor, suitable for direct microcontroller GPIO control without external resistors. Consider the 2% voltage accuracy tolerance for precision applications. Evaluate thermal performance based on the SOT-25 package's power dissipation capabilities under expected load conditions.

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 'A' in the model number denotes the specific Control Enable (CE) pin functionality: High Active with an internal pull-down resistor. The 'MR-G' suffix specifies the SOT-25 surface-mount package and environmental compliance (RoHS/Halogen-free). This series is designed for portable electronic devices requiring efficient power management.

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

Direct substitutes within the same series include other XC6210A variants with different output voltages or packages, such as XC6210A412PR-G (SOT-89-5). Cross-family replacements require matching output voltage, current rating, and package footprint while verifying CE pin logic compatibility.

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

What is the function of the CE pin on the XC6210A412MR-G?

The CE (Control Enable) pin activates the regulator when driven High and places it in stand-by mode when driven Low. As an A-type device, it includes an internal pull-down resistor, ensuring a defined state if the pin is left open.

Does the XC6210A412MR-G require external feedback resistors?

No, the output voltage is fixed internally at 4.1V. External resistors are not needed for voltage setting, unlike adjustable LDO regulators.
