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

What is the function of the CE pin on the XC6210B09APR-G?

The CE (Chip Enable) pin allows the internal regulator circuit to be placed in standby mode. For the B-type series, a High signal activates the regulator, while a Low signal or Open state results in Stand-by mode.

How does the current limiter operate in this device?

The IC features a built-in 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 device during overload or short-circuit conditions.
