2.5 V) and 36 V with two external resistors (see  
Figure 16). This device has a typical output  
impedance of 0.2 . Active output circuitry  
provides a very sharp turnon characteristic,  
making the device an excellent replacement for  
zener diodes and other types of references in  
applications such as onboard regulation,  
adjustable power supplies, and switching power  
supplies.
