The ICL8212 is connected as a programmable zener diode，Zener voltages from 2 V up to 30 V can be programmed by suitably selecting R2．The zener voltage is∶ Because of the absence of internal compensation h the ICL8212，C1 is necessary to ensure stability．Two points worthy of note are the extremely low－knee current(less than 300 μA)and the low dynamic impedance (typically 4 to 7 ohms)over the operating current range of 300 μA to 12 mA.
