LM340, 3-Terminal Positive Regulators

The LM140/LM340A/LM340/LM78XXC monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensa- tion, making them essentially indestructible.

If adequate heat sinking is provided, they can deliver over 1.0A output cur- rent.
