LM7809A - 3-Terminal 1 A Positive Voltage Regulator

Download the LM7809A datasheet PDF. This datasheet also covers the LM7805CT variant, as both devices belong to the same 3-terminal 1 a positive voltage regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The LM78XX series of three-terminal positive regulators is 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.

Features

  • Output Current up to 1 A.
  • Output Voltages: 5, 6, 8, 9, 10, 12, 15, 18, 24 V.
  • Thermal Overload Protection.
  • Short-Circuit Protection.
  • Output Transistor Safe Operating Area Protection.
