LM7800C Datasheet Series 3-terminal Positive Regulators

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM140/LM340A/LM340/LM7800C Series 3-Terminal Positive Regulators May 1999 LM140/LM340A/LM340/LM7800C Series 3-Terminal Positive.

General Description

The 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 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 regulation.
