Description
The MC79XX / MC79XXA/ 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 operating area protection, making it essentially
indestructible.
