В маркировке серии 78ХХ последние две цифры обозначают номинал стабилизируемого напряжения, например: — стабилизация на 5 В; — стабилизация на 12 В; — стабилизация на 15 В и т. Серия 79 предназначена для отрицательного выходного напряжения. Используется для стабилизации напряжения в различных низковольтных схемах. Очень удобно использовать, когда необходимо обеспечить точность подаваемого напряжения, не требуется городить сложных схем стабилизации, а все это можно заменить одной микросхемой и парочкой конденсаторов. Схема подключения LCV Схема подключения L CV довольно проста, для работы необходимо согласно datasheet повесить конденсаторы по входу 0,33 мкФ, и по выходу 0,1 мкФ.
