Load-Line Regulation
Some microprocessor manufacturers require a precisely-
controlled output resistance. This dependence of output
voltage on load current is often termed “droop” or “l(fā)oad line”
regulation. By adding a well controlled output impedance, the
output voltage can effectively be level shifted in a direction
which works to achieve the load-line regulation required by
these manufacturers.
In other cases, the designer may determine that a more cost-
effective solution can be achieved by adding droop. Droop
can help to reduce the output-voltage spike that results from
fast load-current demand changes.
The magnitude of the spike is dictated by the ESR and ESL of
the output capacitors selected. By positioning the no-load
voltage level near the upper specification limit, a larger
negative spike can be sustained without crossing the lower
limit. By adding a well controlled output impedance, the output
