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

What is the function of the CE pin in the XC6210A series?

The CE pin controls the ON/OFF state of the regulator. For the A series, it is High Active with an internal pull-down resistor, meaning the device is enabled when the pin is HIGH and enters stand-by mode when LOW or OPEN.

What is the minimum output capacitance required for the 2.3V output version?

For an output voltage of 2.3V, which falls within the 1.80V to 5.00V range, a minimum output capacitance of more than 1.0µF is recommended.

How does the current limiter operate in this device?

The device features a fixed current limiter and a foldback circuit. When the load current reaches the limit level, the output voltage drops, causing the foldback circuit to further reduce the output current to protect the IC during overload or short-circuit conditions.
