Symmetrical Power Supply "78XX and 79XX"

 Izmantojot 4 micrenes 2x LM7809 un 2x LM7909 izveidojam simetrisko regulējamo barošanas bloku ar spriegumu no 0V līdz 18V , un ar maksimālo strāvu 1,5A.

0V...18V 1.5A Symmetrical Power Supply
2x LM7809, 2x LM7909

Doma šodien gāja tālāk un palielinājām jaudu līdz 5A (...10A) ar strāvas aizsardzību un stabilizāciju.

0V...18V 100mA...5A
Symmetrical Power Supply
78L08, 78L10, 79L08, 79L10
TIP147, TIP142, 2N5401, 2N5551
shēma ir teorētiska, jāpārbauda!!!
