Linear Power Supplies : The Power Supplies show in this circuit designed for is adaptors of CD ROM it can be have output voltage +5V & +12V which use withCD ROM
Figure 1. Linear Power Supplies
The output Current of this circuit narmal is 1A but if we would like to 3A we can be only replacement IC1 & IC2 by which refer form table 1
A power supply (sometimes known as a power supply unit or PSU) is a device or system that supplies electrical or other types of energy to an output load or group of loads.
