FIXED VOLTAGE REGULATOR (NEGATIVE)

Fairchild Semiconductor 

LM79XX/A (KA79XX, MC79XX) FIXED VOLTAGE REGULATOR (NEGATIVE)

3-TERMINAL 1A NEGATIVE VOLTAGE REGULATORS

The LM79XX series of three-terminal negative regulators are available in

TO-220 package and with several fixed output voltages, making them useful

in a wide range of applications. Each type employs internal current limiting,

thermal shut-down and safe area protection, making it essentially indestructible.
