KA78XXE / KA78XXAE
3-Terminal 1 A Positive Voltage Regulator
Features
• Output Current up to 1 A
• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24 V
• Thermal Overload Protection
• Short-Circuit Protection
• Output Transistor Safe Operating Area Protection
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.

Notes:
5. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must
be taken into account separately. Pulse testing with low duty is used.
6. These parameters, although guaranteed, are not 100% tested in production.
