The present disclosure includes circuits and methods for generating bleeding currents. In one embodiment, a pass transistor of a voltage regulator receives a voltage from a feedback circuit. A negative resistance circuit is coupled to a node to produce a bleeding current that turns on when needed and is otherwise off to save power. In one embodiment, the negative resistance circuit includes stacked current mirrors and a resistor. In another embodiment, the resistor has a first terminal that receives the voltage from the feedback circuit and a second terminal is coupled to a constant reference voltage that tracks the input voltage.
