Product Overview

The LM7809, LM78XX series of three terminal positive regulators are available in the TO-220 bundle and with several fixed output voltages. 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 may be used with external components to obtain adjustable voltages and currents.
