Description
The KA78XXE / KA78XXAE series of three-terminal posi-
tive regulators is available in the TO-220 / D-PAK pack-
age 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. If adequate heat sinking is provided, they
can deliver over 1 A output current. Although designed
primarily as fixed-voltage regulators, these devices can
be used with external components for adjustable voltages
and currents.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.
