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.
