Description
The
L78
series of three-terminal positive regulators is available in TO-220,
TO-220FP, D²PAK and DPAK 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 embeds internal current
limiting, thermal shut-down and safe area protection, making it essentially
indestructible. If adequate heat sinking is provided, they can deliver over 1 A output
current. Although designed primarily as fixed voltage regulators, these devices can
be used with external components to obtain adjustable voltage and currents.
