A current limiting circuit. The current limiting circuit includes a device coupled
to an output node of the current limiting circuit. The device is responsive to
magnitude of a signal at the output node. Moreover, the device has a first mode
and a second mode, depending on the magnitude of the signal. The current limiting
circuit also has a regulation component that regulates a voltage at the output
node when the device is in the first mode. The current limiting circuit also has
an element having a current that limits current at the output node when the device
is in the second mode.
