Description
The MC78XXE/LM78XXE/MC78XXAE series of three
terminal positive regulators are available in the
TO-220/D-PAK 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. If adequate heat sinking
is provided, they can deliver over 1A output current.
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain adjustable voltages and currents.
