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