Перспективные LDO-стабилизаторы производства Unisonic Technologies
Компания Unisonic Technologies производит широкий модельный ряд LDO-стабилизаторов, охватывающий диапазон входных напряжений до 80В и выходных токов до 5А. Современные стабилизаторы Unisonic отличаются низким током потребления, наличием всех видов защиты от перегрузок. Ряд изделий имеет управляющий вход Enable, позволяющий существенно снизить ток потребления в спящем режиме.
Продукция доступна в корпусах различных типов, от безвыводных сверхминиатюрных DFN1010 размером 1х1 мм, до классических ТО-252 и ТО-220.
