DESCRIPTION
The L78S00 series of three-terminal positive regu-
lators is available in TO-220 and TO-3 packages
and with several fixed output voltages, making it
useful in a wide range of applications. These regu-
lators can provide local on-card regulation, eliminat-
ing the distribution problems associated with single
point regulation. Each type employs internal current
limiting, thermal shut-down and safe area protec-
tion, making it essentially indestructible. If adequate
heat sinking is provided, they can deliver over 2A
output current. Although designed primarily as fixed
voltage regulators, these devices can be used with
external components to obtain adjustable voltages
and currents.
