7809 +9V Linear Voltage Regulator

  • 7809 monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible.
  • If adequate heat sinking is provided, they can deliver over 1.0A 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.
  • In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents.
