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

How does the Green Operation function affect power consumption?

The Green Operation function automatically switches the regulator between High Speed mode and Power Save mode depending on the load current level, optimizing efficiency by reducing supply current during light loads.

What is the purpose of the internal discharge resistor in the B-type series?

The internal discharge resistor allows the electric charge stored at the output capacitor to be discharged quickly via an N-channel transistor when the CE pin is set to a low level, ensuring the output voltage returns to the VSS level rapidly.
