LM140A Datasheet (National Semiconductor) - Series 3-Terminal Positive Regulators

LM140A, 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 int
