DESCRIPTION

The L7800A series of three-terminal positive

regulators is available in TO-220 and D

2PAK

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 1A

output current. Although designed primarily as

fixed voltage regulators, these devices can be

used

with

external

components

to

obtain

adjustable voltages and currents.
