Description
The L79XXC series of three-terminal negative 
regulators is available in TO-220, TO-220FP, 
TO-3 and D
2
PAK packages and several fixed 
output voltages, making it useful in a wide range 
of applications. These regulators can provide 
local on-card regulation, eliminating the 
distribution problems associated with single point 
regulation; furthermore, having the same voltage 
option as the L78XX positive standard series, 
they are particularly suited for split power 
supplies. If adequate heat sinking is provided, 
they can deliver over 1.5 A output current.
Although designed primarily as fixed voltage 
regulators, these devices can be used with 
external components to obtain adjustable 
voltages and currents.
