LM340 Product details

Description

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.They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulatio
