Been a while since I delved into electronics, but trying my hand at it again. I have a project, simple in nature, and was hoping someone could help me, with regards to the circuit/schematic. I am looking at making a regulated voltage supply. The power supply at max will be about 5 volts at 3 amps. Basically, what I need is a regulated power supply at a fixed 2.5 volts and whatever amps the initial power supply is providing. I only need to ensure that the output voltage stays at 2.5 volts no matter what the initial voltage is and the amps are not changed. If anyone could help me out on something like this I would greatly appreciate it. Thanks!
