Description

The L78xx series of three-terminal positive

regulators is available in TO-220, TO-220FP,

TO-3, 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 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 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.
