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

What is the behavior of the CE pin when left open for the XC6210A type?

For the XC6210A series, the CE pin has an internal pull-down resistor. When left open, the pin voltage floats, potentially leading to undefined states or unstable operation. It is recommended to connect the CE pin to either VIN or VSS to ensure proper functionality.

How does the current limiter function in this regulator?

The IC incorporates a foldback current limiter circuit. When the load current reaches the limit level, the output voltage drops, causing the foldback circuit to further reduce the output voltage and decrease the output current, thereby protecting the device and the output pin.
