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

What is the function of the CL auto-discharge feature in the XC6220D series?

The CL auto-discharge feature allows the IC to quickly discharge the electric charge stored in the output capacitor (CL) through an internal N-channel transistor when the CE pin is set to a low level, shortening the time until the VOUT pin reaches the VSS level.

How does the Green Operation function affect the supply current?

The Green Operation function monitors the output current and automatically switches the IC between high-speed mode and power-save mode. In power-save mode, the typical supply current is reduced to 8μA, which greatly extends battery life during light load conditions.
