LM7809 Datasheet (Fairchild Semiconductor) - 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS

LM7809, 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS

LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE) 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS The LM78XX series of three-terminal positive regulators are available in the TO-220/D-PAK 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 area protection, making it essentially indestructible.

If adequate heat sinking is provided, they can deliver over 1A output current.
