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

How does the CE pin behave when left open?

Due to the internal pull-down resistor, leaving the CE pin open results in a logic low state, placing the device in the Operation OFF (Stand-by) mode.

What happens to the output voltage during shutdown?

The internal auto-discharge switch activates, rapidly discharging the output capacitor CL so that the VOUT pin quickly returns to the VSS level.
