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

How does the Green Operation function work?

The Green Operation function monitors the output current and automatically switches the IC between high-speed mode and power-save mode to optimize power consumption under varying load conditions.

What is the purpose of the CL auto-discharge feature?

The CL auto-discharge feature uses an internal N-channel transistor to rapidly discharge the output capacitor when the control pin is set to low, shortening the time until the output voltage reaches the ground level.
