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

How does the Green Operation function affect the supply current?

The Green Operation function monitors the output current and automatically switches between High Speed mode for heavy loads and Power Save mode for light loads, significantly reducing supply current during low-demand periods.

What is the purpose of the auto-discharge resistor in this model?

The auto-discharge resistor connects between the VOUT and VSS pins to rapidly discharge the electric charge stored in the output capacitor when the IC is turned off via the CE pin, ensuring the output voltage quickly returns to the ground level.
