Hello everyone, I am building a small circuit with an extra SRAM, for the arduino. I am using two 23k256 and a TXB0108 logic level shifter. I am thinking of powering the chips simply by voltage divider from 5 volts, the whole circuit is using. I wonder how much current should I leave for the chip…

voltage divider and current for 23k256

No, just think about the impedance of the output of the divider.
