AS78XXA 1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR Description The DIODES™ AS78XXA series are three-terminal positive voltage regulators designed for a wide variety of applications including local, on-card regulation. The AS78XXA are plete with internal current limiting, thermal shutdown protection, and safe-area pensation which make them virtually immune from output overload. If adequate heat sinking is provided, these regulators can deliver output currents of up to 1A. The AS78XXA are available in TO-252-2 (3), TO-252-2 (4), TO-252-2 (5), TO-220-3, TO-220-3 (2), and TO-220F-3 packages.
