5V 10A Power Supply Circuit Diagram
Table of Contents
With the help of this circuit you can make high ampere constant voltage Power supply like 5amp-10amp-20amp-50amp….. and so on. 7805 high current voltage regulator circuit can increase the load current capacity by adding a transistor.
78XX Three-terminal regulator manual contains positive regulators using NPN transistors, otherwise negative regulators (79xx) use PNP transistors. The following is an example of a 5V DC voltage regulator circuit using IC 7805, which aims to increase the load current of 1A IC 7805 to a higher level (10A). The outermost transistor uses the highest load current. Here I explained how you can make 5v 10a power supply.

Use 5Volt DC Fan With This Circuit (With Transistor) If using For Long Time
By adding three complementary TIP2955 transistors, the simple voltage regulator circuit below has a rated load current of up to 10 A. The charging current capacity can be changed by increasing or decreasing the number of TIP2955. A resistance of 4.7 To 10 Ohm can be used to prevent current flooding and stabilize the input voltage of IC 7805.
Since the no-load current capacity of 7805 is greater than 1 A, it is necessary to provide 1 A of output current as a safety fuse on the IC and prevent high current transients. On the IC 7805 and TIP2955 transistors, a heat sink should be installed so that the load current generates enough heat, For the 7905 negative regulator you need to replace the TIP2955 transistor with another model, such as 2N3055 . Hope this brief description helps increase the load current of the 7805 regulator circuit
