General Description
The LM78XX series 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.
