1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR

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 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.

Applications

 High Efficiency Linear Regulator

 Post Regulation for Switching Supply

 Microprocessor Power Supply

 Mother Board

Notes: 1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.

4. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
