Standard Regulator 9 Volt 1 Amp 3 Pin 3+ Tab


The LM78XX series of three terminal positive regulators are useful in a wide range of applications. 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. 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 (2.2A peak)
  • Thermal Overload Protection
  • Short Circuit Protection
  • Output Transistor Safe Operating Area Protection
