I would like to build the Dual Supply Dynamic Electronic load, that Jay_Diddy_B is developing. I want to use the VAC Supply Option. I have a LT1019_2.5v, in my stocks.
- Do I need to trim the LT1019, at all, for the needed accuracy, for this circuit?
- If not, how do I need to terminate the pin?
- If so, could someone help me with the math, to do a three resistor trim, like the one shown for the 5.120v model, on page 9, top-left corner. Please. How important is it that the resistors are 1% Low TC Cermet?
The LT6656 option is above $6. But, it may be easier to deal with?
What about just a good old zener diode?
I do not want to use the temp pin, for anything. Just terminate it to an unconnected pad?
The device will be mounted in a big honking, Realistic, defunked (get it? <grin>), 100amp, stereo chassis. It uses one of the huge heat sinks and an 120vac computer case fan, for cooling.
Thank you, for your help.
