BCD AS7809D-E1 1a 3-terminal positive voltage regulator Datasheet

Data Sheet
1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR
General Description
Features
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.
·
·
·
AS78XX

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability.
