Abstract:
An electronic circuit. The electronic circuit includes a pass transistor having a channel coupled between an input node and an output node. An error circuit is coupled thereto and configured to control the amount of current flowing through the pass transistor. The electronic circuit may further include a feedback node. A current limiting circuit is coupled to both the feedback node and the error circuit. The current limiting circuit is configured to limit an amount of current provided to the pass transistor by the error circuit based on a on a feedback voltage present on the feedback node and a current through a current mirror circuit, and therefore limits the output current provided by the electronic circuit.
