Abstract: A linear regulator includes a pass transistor, a buffer transistor, and a low-pass filter circuit. The pass transistor is configured to pass a current from an input terminal to an output terminal. The buffer transistor is coupled to the input terminal and the pass transistor, and is configured to control the pass transistor. The low-pass filter circuit is coupled to the input terminal and the buffer transistor, and is configured to modulate a threshold voltage of the buffer transistor responsive to a transient at the input terminal.
