DESCRIPTION
The L7800 series of three-terminal positive regula-
tor is available in TO-220, ISOWATT220 and TO-3
packages and with several fixed output voltages
making it useful in a wide range of applications.
These regulators can provide local on-card regula-
tion, eliminating the distribution problems associ-
ated with single point regulation. Each type employs
internal current limiting, thermal shut-down and safe
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.
