Positive voltage regulator ICs
Datasheet - production data
Features
Output current up to 1.5 A Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; V Thermal overload protection Short circuit protection Output transition SOA protection 2 % output voltage tolerance (A version) Guaranteed in extended temperature range version)
Description

The L78 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
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
embeds 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.
