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

How does the Green Operation function improve efficiency?

The Green Operation function automatically switches the IC between high speed mode for heavy loads and power save mode for light loads, significantly reducing supply current during low-power operation.

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

The CL auto-discharge feature uses an internal N-channel transistor to quickly discharge the output capacitor when the IC is turned off, shortening the time required for the output voltage to reach the ground level.
