A switching resistance linear regulator. The regulator comprises an output
terminal producing a regulated output voltage, a first comparator, a
second comparator, a first sourcing circuit coupled to the output
terminal, and a first sinking circuit coupled to the output terminal. The
first comparator compares a feedback signal representative of the output
voltage and a first sourcing reference signal that is less than a
reference signal. The second comparator compares the feedback signal and
a first sinking reference signal that is greater than the reference
signal. The first sourcing circuit is configured to be responsive to the
first comparator by sourcing a first current to the output terminal. The
first sinking circuit is configured to be responsive to the second
comparator by sinking a second current from the output terminal.
