LM78XXE

    The MC78XXE/LM78XXE/MC78XXAE 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 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.
