摘要： A low-dropout regulator with inrush current limiting capabilities may include an output terminal to provide an output signal, a first current branch comprising a pass device connected to the output terminal, and a second current branch comprising a driver transistor and a current generator. The low-dropout regulator may further include an error amplifier to control the driver transistor. The error amplifier may have a first input node to apply a reference signal, and a second input node coupled to the output terminal. The low-dropout regulator may include a current mirror to couple the second current branch to the first current branch. The current mirror is configured to mirror a current in the second current branch to the output current branch.
