Power Supply +12V. -12V and +5V

Schematic

The application of this circuit is in the use of operational amplifiers which require multiple power supply +12 V and -12V. It also still provides a +5 V power supply for other circuits such as digital circuits.
A symmetric power supply mostly used in amplifiers. If you want to create a symmetric power supply with a current of more than 1 amp, you would just remove IC79** and IC78** (output current of this IC is 1 amp), replace D1, D2, D3, D4 with a diode bridge with a range 35A, and replace the capacitor by increasing the charge and voltage.
