Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community LM340, LM340A, LM7805, LM7812, LM7815 SNOSBT0L – FEBRUARY 2000 – REVISED SEPTEMBER 2016 LM340, LM340A and LM7805 Family Wide VIN 1.

General Description

The LM340 and LM7805 Family monolithic 3-terminal positive voltage regulators employ internal currentlimiting, thermal shutdown and safe-area compensation, making them essentially indestructible.

If adequate heat sinking is provided, they can deliver over 1.5-A 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.

Key Features

  • 1 Output Current up to 1.5 A.
  • Available in Fixed 5-V, 12-V, and 15-V Options.
  • Output Voltage Tolerances of ±2% at TJ = 25°C (LM340A).
  • Line Regulation of 0.01% / V of at 1-A Load (LM340A).
  • Load Regulation of 0.3% / A (LM340A).
  • Internal Thermal Overload, Short-Circuit and SOA Protection.
  • Available in Space-Saving SOT-223 Package.
  • Output Capacitance Not Required for Stability 2.
