Data Sheet 1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR General Description Features 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 are provided, these regulators can deliver output currents up to 1A. · · · · · The AS78XXA are available in TO-252-2 (1), TO252-2 (3), TO-252-2 (4), TO-220-3 and TO-220F-3 packages. 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 Applications · · · · High Efficiency Linear Regulator Post Regulation for Switching Supply Microprocessor Power Supply Mother Board TO-220-3 TO-252-2 (1) AS78XXA TO-220F-3 TO-252-2 (3) TO-252-2 (4) Figure 1.
