100mA POSITIVE VOLTAGE REGULATOR
AS78LXX
General Description
Features
·
·
·
Output Current up to 100mA
The AS78LXX series are three terminal positive regu-
lators designed for a wide variety of applications
including local, on-card regulation.
Fixed Output Voltages of 5V, 12V and 15V
Output Voltage Accuracy of ±5% over the Full
Temperature Range
This series of regulators are complete with internal
current limiting, thermal shutdown protection, and
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-
