... Layout Considerations The typical application employing an ISL6506 is a fairly straight forward implementation. Like with any other linear regulator, attention has to be paid to the few potentially sensitive small signal components, such as those connected to sensitive nodes or those supplying critical bypass current ...

... ESR. Transistor Selection/Considerations The ISL6506, ISL6506A usually requires one P-Channel and two N-Channel MOSFETs. All three of these MOSFETs are utilized as ON/OFF switching elements. One important criteria for selection of transistors for all the switching elements is package selection for efficient removal of heat ...
