I need constant current 100mA source (120 channels of them) with as much low output tolerances as possible (so I don't want to use for example LM317 +resistors).
I found Supertex CL7 chip (+- 5%)
But there is problem, because I need to circuit my load one one side to GND. Here in this Chip load is between Vdd and Vout. Do you think I can circuit my load between Vout and GND?
Do you maybe have any other solution?
