Is it OK to plug the 3.3V to the ground pin with only about 250 ohms of resistance. Is that bad for some reason?
Thanks.
Thanks.
3.3V/250 ohm = 13.2 mA, its like a couple of leds, so should not hurt, but why waste power.
Surely they won't ripple any more. The voltage at the mid-point of the divider will have the same amount of ripple with 10k:10k as with 120:120.
It will have a higher source impedance, is that the issue? That can be fixed with some bulk decoupling between the midpoint and ground - as often
seen with a virtual ground.
