AS78LXX
General Description
Features
·
·
Output Current up to 100mA
Fixed Output Voltages of 5V, 12V, 15V, 18V and
24V
The AS78LXX series are three terminal positive regu-
lators designed for a wide variety of applications
including local, on-card regulation.
·
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.
