... Applications Information The basic LP3203 applicaton circuit is shown inTypical Application Circuit. External component selection is determined by the maximum load current and begins with the selection of the inductor value and operating frequency followed by CIN and COUT. Inductor selection The output inductor is selected to limit the ripple current to some predetermined value ...
