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

Verify the specific package type matches the design requirements, as the XC6210 series is available in SOT-25, SOT-89-5, and USP-6B configurations. Confirm that the CE pin logic aligns with the system control signals, as Type A devices require a High Active signal with a pull-down resistor. Ensure compliance with environmental standards by checking for the Halogen and Antimony-free designation associated with the suffix.

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

Select this component for applications requiring stable regulation under varying load conditions with minimal voltage drop. The fixed 5.0V output makes it suitable for powering digital logic or peripheral interfaces directly from single-cell lithium batteries. Consider the thermal dissipation capabilities of the SOT-25 package relative to the expected power loss during operation.

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

What is the minimum required output capacitor value for the XC6210A502MR-G?

For an output voltage of 5.00V, which falls within the 1.80V to 5.00V range, a minimum output capacitor (CL) of 1.0μF is required.

How does the CE pin function on the XC6210A series?

The XC6210A series features a High Active CE pin with an internal pull-down resistor. Applying a High signal activates the regulator, while a Low signal places it in standby mode.
