DESCRIPTION
TO-220
The UTC LM79XXA series of three-terminal negative
regulators is available 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.
