AS78XXA

1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR

Description

Features

The AS78XXA series are three terminal positive voltage regulators

designed for a wide variety of applications including local, on-card

regulation.



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

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.



Internal Short Circuit Current Limiting

Internal Thermal Overload Protection

Output Transistor Safe-area Protection

Low Load Regulation

Stable Performance in High Temperature
