L78L

Positive voltage regulators

Datasheet

production data

Description

The L78L series of three-terminal positive

regulators employ internal current limiting and

thermal shutdown, making them essentially

indestructible. If adequate heat-sink is provided,

they can deliver up to 100 mA output current.

They are intended as fixed voltage regulators in a

wide range of applications including local or on-

card regulation for elimination of noise and

distribution problems associated with single-point

regulation. In addition, they can be used with

power pass elements to make high-current

voltage regulators. The L78L series used as

Zener diode/resistor combination replacement,

offers e improvement along with lower quiescent

current and lower noise.

Features

•

Output current up to 100 mA

•

Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18;

24 V thermal overload protection

•

Short-circuit protection

•

No external components are required

•

Available in either ± 4% (A) or ± 8% (C)
