DESCRIPTION  
Z
The TL431 is a programmable shunt voltage  
reference with guaranteed temperature stability  
over the entire temperature range of operation.  
The output voltage may be set to any value  
between 2.5V and 36V with two external resistors.  
The TL431 operates with a wide current range  
from 1 to 100mA with a typical dynamic  
impedance of 0.22.
