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

How does the CE pin behave when left open?

For the N-series, an internal pull-down resistor maintains the CE pin voltage at a low level, placing the device in the operation OFF (stand-by) state when the pin is open.

What is the purpose of the auto-discharge function?

The auto-discharge function allows the electric charge stored in the output capacitor to be drained via an internal switch when the CE signal is low, causing the output voltage to quickly return to the ground level.
