LM-340 Datasheet (National Semiconductor) - Series 3-Terminal Positive Regulators

LM-340, Series 3-Terminal Positive Regulators

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
