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

How does the Green Operation function manage power consumption?

The Green Operation feature monitors the output current level and automatically switches the regulator between a High Speed mode for heavy loads and a Power Save mode for light loads to minimize supply current.

What is the purpose of the internal auto-discharge resistor in the D-type?

The internal auto-discharge resistor connects between the VOUT and VSS pins when the CE pin is pulled low, allowing the electric charge stored in the output capacitor to dissipate quickly.
