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

How does the IC handle output capacitor discharge?

The device features a CL auto-discharge function that activates when the CE pin is set to a low level, discharging the output capacitor through an internal resistance.

What is the status of the output when the CE pin is left open?

Leaving the CE pin open results in an unstable state; it should be connected to either VIN or VSS to ensure predictable operation.
