7 805b description this series of fixed - voltage monolithic integrated - circuit voltage regulators is designed for a wide range of applications. these applications include on - card regulation for elimination of noise and distribution problems associated with single - point regulation. in addition, they can be used with power - pass elements to make high - current voltage regulators. each the interna l of these regulators can deliver up to 1.0 a of output current. limiting and termal shutdown features of these regulators make them essentially immune to overload. features output current in excess of 1.0a no external components required internal short circuit current limiting internal thermal overload protection output transistor safe - area compensation output voltage offered in 4% tolerance int e rn a l blo c k di g r a m package beijing estek electronics co.,ltd 1
