Description

ОПИСАНИЕ
LM138/LM238/LM338 — это регуляторы положительного напряжения с тремя терминалами и возможностью настраиваться, способные обеспечивать ток свыше 5 А в диапазоне выходных напряжений от 1,2 В до 32 В. Эти устройства чрезвычайно просты в использовании и требуют всего двух резисторов для настройки выходного напряжения. Тщательная схемотехника обеспечила исключительную стабильность нагрузки и линейное регулирование, сравнимую с многими коммерческими источниками питания. Семейство LM138 поставляется в стандартной трехконтактной транзисторной упаковке.
ГАРАНТИРОВАННЫЙ ПИК-ТОК ВЫХОДА 7 А
ГАРАНТИРОВАННЫЙ ТОК ВЫХОДА 5 А
НАСТРОЙКА ВЫХОДНОГО НАПРЯЖЕНИЯ ДО 1,2 В
ЛИНЕЙНОЕ РЕГУЛИРОВАНИЕ, КАК ПРИМЕР, 0,005% / В
НАГРУЗОЧНОЕ РЕГУЛИРОВАНИЕ, КАК ПРИМЕР, 0,1%
ГАРАНТИРОВАННОЕ ТЕРМОРЕГУЛИРОВАНИЕ
ПОСТОЯННОЕ ПРЕДЕЛЬНОЕ ПОТОКА ПО ТЕМПЕРАТУРЕ
СТАНДАРТНАЯ ТРЕХКОНТАКТНАЯ ТРАНЗИСТОРНАЯ УПАКОВКА
