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 be level in the direction that works to
control the voltage spike coincident with fast load current
demand changes.
