L78Sxx
L78SxxC
2 A positive voltage regulators
Features
■ Output current to 2 A

■ Thermal overload protection
■ Short circuit protection
■ Output transition SOA protection
Description
The L78Sxx series of three-terminal positive
regulators is available in TO-220 and TO-3
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. 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 2 A output
current. Although designed primarily as fixed
voltage regulators, these devices can be used
with external components to obtain adjustable
voltages and currents.
