100mA POSITIVE VOLTAGE REGULATOR
General Description
Features
AS78LXX
The AS78LXX series are three terminal positive regu- · Output Current up to 100mA
lators designed for a wide variety of applications · Fixed Output Voltages of 5V, 12V, 15V, 18V and
including local, on-card regulation.
24V
· Output Voltage Accuracy of ±5% over the Full
This series of regulators are complete with internal
Temperature Range
current limiting, thermal shutdown protection, and · Internal Short Circuit Current Limiting
safe-area compensation which make them virtually
immune from output overload. If adequate heat sinking
are provided, these regulators can deliver output cur-
rents up to 100mA.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
