The LT® 1529/LT1529-3.3/LT1529-5 are 3A low dropoutregulators with micropower quiescent current and shutdown.The devices are capable of supplying 3A of outputcurrent with a dropout voltage of 0.6V. Designed for usein battery-powered systems, the low quiescent current,50mA operating and 16mA in shutdown, make them anideal choice. The quiescent current is well controlled itdoes not rise in dropout as it does with many other lowdropout PNP regulators.
