DESCRIPTION  
The UTC 79TXXA series of three-terminal negative  
regulators are available in TO-263 package and with several  
fixed output voltage, making them useful in a wide range of  
application. Each type employs internal current limiting,  
thermal shut-down and safe area protection, making it  
essentially indestructible.
