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.
