3-Terminal 5V 1A Positive Voltage Regulator

The LM7805 three terminal positive regulators is available in the TO-220 package with a fixed output voltage, making it useful in a wide range of applications. It employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, it can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.


  • Output current up to 1A
  • Output voltage: 5V
  • Temperature: -40°C to +125°C
  • Thermal overload protection
  • Short circuit protection
  • Output transistor safe operating area protection
