Negative power supply, with the protection amp.
It start at -2 volts and a maximun -22.5 Volts.
It is limited to 500 mA.
If you try to build it so remember to use transistors and resistors that can handle 10 watts which it can deliver.
This supply I make as a school project
the works and is tested.
If you have any questions, you should just ask
Only the transistor on tghe top line need to be a power transitor here i used Tip 41 3 Amp.
allso the 1.2 ohm resistor need to be a 10 Watt power resistor,
for the small transistor I used Bc557
resistor are all 1/4 watt
