Description

The MC78XX/LM78XX/MC78XXA 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.
