Preliminary Datasheet
3-TERMINAL 1A POSITIVE VOLTAGE REGULATOR
General Description
Features
AS78XX
The AS78XX series are three terminal positive regula- · Output Current up to 1A
tors designed for a wide variety of applications includ- · Fixed Output Voltages of 5V, 12V and 15V
ing local, on-card regulation.
· Output Voltage Accuracy of ±4% over the Full
Temperature Range
The AS78XX are complete with internal current limit- _{· Internal Short Circuit Current Limiting}
ing, thermal shutdown protection, and safe-area com- _{· Internal Thermal Overload Protection}
pensation which make them virtually immune from
output overload. If adequate heat sinking are provided,
these regulators can deliver output currents up to 1A.
