Description
The KA79XX / KA79XXA / LM79XX series of three-termi-
nal negative regulators are available in a TO-220 pack-
age with several fixed output voltages, making them
useful in a wide range of applications. Each type employs
internal current limiting, thermal shutdown, and safe
operating area protection.
