I am supposed to design a power supply to a project. I have 3 alternative power supply designs for this purpose. However, one of them sucks huge current while giving enough current. My design is given below:
I have searched a lot to find a way to limit this current. I have found current limiter including 2 transistor and the power supply including current limiter is given below:
As it can be seen, Although stated as low voltage drop, just after the limiting block, voltage almost hit the ground. Please offer me a way to limit this current somehow by depending on the design, please. Thanks in advance.
