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, balancing speed and low power consumption.

What is the purpose of the CE pin?

The CE pin controls the ON/OFF state of the regulator; pulling it low shuts down the IC to reduce standby current.
