1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR
AS78XXA
General Description
Features
·
·
Output Current up to 1A
Fixed Output Voltages of 5V, 6V, 8V, 9V, 12V,
15V and 18V
The AS78XXA series are three terminal positive
voltage regulators designed for a wide variety of appli-
cations including local, on-card regulation.
·
Output Voltage Accuracy of ±4% over the Full
Temperature Range
The AS78XXA are complete with internal current lim-
iting, 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.
·

·
·
Internal Short Circuit Current Limiting
Internal Thermal Overload Protection
Output Transistor Safe-area Protection
Low Load Regulation
Stable Performance in High Temperature
The AS78XXA are available in TO-252-2 (1), TO-
252-2 (3), TO-252-2 (4), TO-220-3 and TO-220F-3
packages.
