Positive voltage regulator ICs

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.
