LM340 Description

The LM340 and LM7805 Family monolithic 3-terminal positive voltage regulators employ internal currentlimiting, thermal shutdown and safe-area pensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.5-A output current. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and...
