Abstract
A low-drop out voltage regulator includes a pass element arranged between an input terminal and an output terminal, a feedback network configured to produce a feedback voltage derived from an output voltage, and an error amplifier configured to drive the pass element as a function of a difference between the feedback voltage and a reference voltage. An output transistor coupled in series with the pass element is controlled by a mode selection circuit. In response to assertion of a mode selection signal, the mode selection circuit turns on the output transistor to sink a current with a controlled magnitude from the output node. In response to de-assertion of the mode selection signal, the mode selection circuit sinks a current with a controlled magnitude from a control terminal of the output transistor to turn off the output transistor at a controlled rate.
