DESCRIPTION
The L7800 series of three-terminal positive regula-
tor is available in TO-220, ISOWATT220 and TO-3
packages and with several fixed output voltages
making it useful in a wide range of applications.
These regulators can provide local on-card regula-
tion, eliminating the distribution problems associ-
atedwithsinglepointregulation. Eachtypeemploys
internal current limiting,thermalshut-down and safe
area protection, making it essentially indestructible.
Ifadequate heatsinkingisprovided, theycandeliver
over 1Aoutput current. Although designed primarily
as fixed voltage regulators, these devices can be
usedwith external components to obtainadjustable
voltages andcurrents.
