  • The LM78XX series of three terminal positive regulators are available in the TO-220 package. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current.
  • These devices can be used with external components to obtain adjustable voltages and currents. Available output voltages: 5, 6, 8, 9, 10, 12, 15, 18, and 24V.
