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 pro-
tection, 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 com-
ponents to obtain adjustable voltages and currents.
