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.
