LM340 12V 1A Positive Voltage Regulator – Datasheet

The LM340 is a monolithic 3-terminal positive voltage regulator that employs internal current-limiting, thermal shutdown, and safe-area compensation making them essentially indestructible. If adequate heat sinking is provided, It can deliver over 1.0A output current. It is intended as a fixed voltage regulator in a
wide range of applications including local (on-card) regulation for the elimination of noise and distribution problems associated with single-point regulation.

In addition, to use as a fixed voltage regulator, this device can be used with external components to obtain adjustable output voltages and currents. Considerable effort was expended to make the entire series of regulators easy to use and minimize the number of external components.
