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

How does the Green Operation function affect performance?

It automatically switches between high-speed mode for heavy loads and power-save mode for light loads to optimize efficiency.

What happens to the output voltage when the CE pin is pulled low?

The CL auto-discharge circuit activates, rapidly draining the output capacitor to bring the VOUT pin to the VSS level.
