AS78XXA
1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The AS78XXA series are three terminal positive voltage regulators
designed for a wide variety of applications including local, on-card
regulation.
The AS78XXA 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 is
provided, these regulators can deliver output currents up to 1A.
The AS78XXA are available in TO-252-2 (3), TO-252-2 (4), TO-252-2
(5), TO-220-3 and TO-220F-3 packages.
Features
Output Current up to 1A
Fixed Output Voltages of 5V, 6V, 8V, 9V, 12V, 15V and 18V
Output Voltage Accuracy of ±4% over the Full Temperature
Range
Internal Short Circuit Current Limiting
Internal Thermal Overload Protection
Output Transistor Safe-area Protection
Low Load Regulation
Stable Performance in High Temperature
