Abstract:
The regulator with low dropout voltage comprises an error amplifier and an output stage comprising an output transistor and a buffer circuit comprising an input connected to the output node of the error amplifier, an output connected to the output transistor, a follower amplifier connected between the input and the output of the buffer circuit. The buffer circuit furthermore comprises a transistor active load connected to the output of the follower amplifier and a negative feedback amplifier arranged in common gate configuration and connected between the output of the follower amplifier and the gate of the transistor of the active load.
