linear regulator


The linear regulator is the basic building block of nearly every power supply used in electronics. The IC linear regulator is so easy to use that it is virtually foolproof, and so inexpensive that it is usually one of the cheapest components

Todaymicroprocessors are placing ever greater demands upon power system design. Most state of the art devices now require a 3.3 V bus and therefore necessitate some means of stepping down the existing 5V system supply. To complicate matters further,

A dynamic game approximation for a linear regulator problem with a log-barrier state constraint

AbstractAn exact supremum-of-quadratics representation for log-barrier functions is developed for, and subsequently applied in, a state-constrained linear regulator problem. By approximating this representation, it is shown that this regulator problem can be
