Features
Description
The L78Lxx 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.
Table 1.
September 2007
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 ±5% (AC) or ±10% (C)

In addition, they can be used with power pass
elements to make high-current voltage regulators.
The L78Lxx series used as Zener diode/resistor
combination replacement, offers an effective
output impedance improvement of typically two
orders of magnitude, along with lower quiescent
current and lower noise.
