Elbert, you have tell us a little more of what this circuit need to do, like bandwidth, switching speed, voltages, what it is for, etc. if you need simply a limited current source, check out what a LM317 can do for you. Cheers Friedel

Hello members, I need some help with a current boost circuit. The primary powersuppy of the circuit is 5V. I have an output which is switchable between 1.8V, 3.3V and 5 Volts, delivering a maximum current of 60mA. However, I need about 200 mA, with a 250mA current limit. I thought about a simple voltage follower opamp circuit with a current boost circuit at the output of the opamp. I searched on several websites of the Hardware chapter on the chipdir, but did not find an applicable circuit. Any ideas?
