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

What is the function of the CE pin on the XC6210D28AMR-G?

The CE (Chip Enable) pin controls the operational state. For the D-type series, the device is active when the CE pin is at a Low level and enters stand-by mode when the CE pin is at a High level.

How does the current limiter operate in this regulator?

The IC features a fixed current limiter circuit and a foldback circuit. When the load current reaches the limit level, the output voltage drops, triggering the foldback circuit to further reduce the output current, providing protection against overloads and short circuits.
