Datasheet - production data  
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.
