    摘要： This document discusses, among other things, a regulator circuit. The regulator circuit can controllably connect a first voltage to an inductor using a first switch and can controllably connect a second voltage to the inductor using a second switch. The first switch can be turned off and the second switch can be turned on for a duration proportional to a difference between the first voltage and a third voltage, divided by the first voltage. The first switch can be turned off and the second switch can be turned on for a duration proportional to the third voltage divided by the first voltage. One of the first or third voltages can correspond to a desired output voltage.

    摘要： The present invention includes a pass transistor that limits current drawn from a circuit without using a series resistor and while drawing minimal current from an external supply. A current mirror of the output current is formed and compared to a reference current. When the output current increases, the mirror current increases proportionally, and when a threshold is crossed, the pass transistor is turned off. The pass transistor is biased from a charge pump that provides a voltage, a current from which a current mirror is drawn that controls the pass transistor.
