Dear All,
I have used 3.3v zener resistor combination for reference voltage (Vref) on Inverting Pin of LM358 IC battery low/high voltage circuit. I am very much confused on Current which requires zener to run correctly. Some datasheet say minimum current as 76mA and maximum continous current as 276mA (datasheet attached). Someone says minimum current should be 10mA and so. But, I didn't get correct voltage value of zener (3.3v). Any help on this would be highly appreciated.
Thanks
