typical output impedance is 200m. The  
LX432 series operates with an operating  
current as low as 80µA, making these  
devices suitable for portable and  
micropower applications.

The LX432 is offered in 3 and 5-Pin  
SOT-23 or TO-92 packages, and is a drop-  
in replacement for the TLV431 and  
SC431L devices.
