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

What is the minimum recommended output capacitor value for the XC6210A382DR-G?

For an output voltage of 3.8V, which falls within the 1.80V to 5.00V range, the minimum recommended output capacitor (CL) is 1.0µF ceramic.

How does the CE pin function in the XC6210A series?

The CE pin is active-high. Applying a high voltage level activates the regulator, while a low voltage level places the IC in standby mode. The A-series includes an internal pull-down resistor to ensure the device remains off when the pin is open.

What protection features are integrated into the XC6210A382DR-G?

The device includes a constant current limit circuit and a short-circuit protection mechanism utilizing a foldback circuit to reduce output current during fault conditions.
