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

How does the CE pin function operate for the XC6210D series?

For the XC6210D series, the CE pin is active-low. Applying a low signal activates the regulator, while a high signal places the IC into stand-by mode. This variant does not include an internal pull-up resistor.

What protection features are integrated into the XC6210D28ADR-G?

The device includes a built-in constant current limiter circuit and a foldback circuit. These features protect against overload conditions by reducing output current when the limit is reached and providing short-circuit protection.
