KA78XXE / KA78XXAE
3-Terminal 1 A Positive Voltage Regulator
Features
Description
•
•
•
•
•
The KA78XXE / KA78XXAE series of three-terminal positive regulators is available in the TO-220 / D-PAK package 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.
Output Current up to 1 A
Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24 V

Ordering Information
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes:
33. To specify an output voltage, substitute voltage value for “XX”. A common ground is required between the input and
the output voltage. The input voltage must remain typically 2.0 V above the output voltage even during the low
point on the input ripple voltage.
34. CI is required if regulator is located an appreciable distance from power supply filter.
35. CO improves stability and transient response.
