DESCRIPTION
The L78S00 series of three-terminal positive
regulators 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 regulators can provide local on-card
regulation, eliminating the distribution problems
associated with single point regulation. Each type
employs
shut-down and safe area protection, 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.
