I need to set-up a circuit that can protect a load from currents above 200 mA. I use 10 Volts VDC from the power supply and I need all 10 volts to go across the load and stay constant. I will be adjusting the load resistance from between 750 - 100k ohms and the voltage drop needs to stay at 10 volts. Some slight variation will work but we are going to be trimming potentiometers, so the voltage drop needs to be constant 10 volts with any change in resistance of the load.
If anyone has any ideas on how i can design this circuit, feel free to post, it would be much appreciated.
Also if anyone knows if I am better off using FETS or BJT's. With BJT's I have used, the voltage drop due to Vbe doesn't fit my specifications.
Thanks in Advance
