Description

The LM140A LM140 LM340A LM340 LM7800C monolithic 3-terminal positive voltage regulators employ internal current-limiting thermal shutdown and safe-area compensation making them essentially indestructible If adequate heat sinking is provided they can deliver over 1 0A output current They are intended as fixed voltage regulators in a www.DataSheet4U.com wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point re
