Data Sheet 1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR General Description The AS78XX series are three terminal positive regulators designed for a wide variety of applications including local, on-card regulation. The AS78XX 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 AS78XX are available in TO-220-3 and TO-252-2 (1) packages. AS78XX Features · · · · · · Output Current up to 1A Fixed Output Voltages of 5V, 8V, 9V, 12V and 15V Output Voltage Accuracy of ±4% over the Full Temperature Range Internal Short Circuit Current Limiting Internal Thermal Overload Protection Output Transistor Safe-area Protection Applications · · · · High Efficiency Linear Regulator Post Regulation for Switching Supply Microprocessor Power Supply Mother Board TO-220-3 TO-252-2 (1) Figure 1.
