Description
The KA78XXE/KA78XXAE series of three-terminal posi-
tive regulator 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.
