7809 General Description :

The LM7809 of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them 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.

LM7809 Features :

  • Output Current up to 1A
  • Output Voltages of 9 volt
  • Thermal Overload Protection
  • Short Circuit Protection
  • Output Transistor Safe Operating Area Protection
