Hi guys! Need some help. Attached is a circuit that I designed. The Vin is 7.2V and the Vout (at the load) is 5V. Basically, that's exactly what I wanted!
Anyway - can someone please help me with the understanding of the circuit. I know the basics but I'm a bit stumped on the use of the op-amp (I think it's used for smoothening out the voltage or something) and the configuration of the transistors. I know that the BJTs are used for current limitation but the way they are connected here doesn't make much sense.
Also can someone suggest another type of BJT to use coz I blew the 3904s the first time around!
Thanks
