Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers  
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor  
product management systems do not have the ability to manage part nomenclature that utilizes an underscore  
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain  
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated  
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please  
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

KA78XXE / KA78XXAE  
3-Terminal 1 A Positive Voltage Regulator  
Features  
Description  
• Output Current up to 1 A  
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.  
• 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

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. 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.

DISCLAIMER  
FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE  
RELIABILITY, FUNCTION, OR DESIGN. TO OBTAIN THE LATEST, MOST UP-TO-DATE DATASHEET AND PRODUCT INFORMATION, VISIT OUR WEBSITE  
AT HTTP://WWW.FAIRCHILDSEMI.COM. FAIRCHILD DOES NOT ASSUME ANY LIABILITY ARISING OUT OF THE APPLICATION OR USE OF ANY  
PRODUCT OR CIRCUIT DESCRIBED HEREIN; NEITHER DOES IT CONVEY ANY LICENSE UNDER ITS PATENT RIGHTS, NOR THE RIGHTS OF OTHERS.  
THESE SPECIFICATIONS DO NOT EXPAND THE TERMS OF FAIRCHILD’S WORLDWIDE TERMS AND CONDITIONS, SPECIFICALLY THE WARRANTY  
THEREIN, WHICH COVERS THESE PRODUCTS.  
LIFE SUPPORT POLICY  
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE  
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.  
As used herein:  
1. Life support devices or systems are devices or systems which, (a) are  
intended for surgical implant into the body or (b) support or sustain  
life, and (c) whose failure to perform when properly used in  
accordance with instructions for use provided in the labeling, can be  
reasonably expected to result in a significant injury of the user.  
2. A critical component in any component of a life support, device, or  
system whose failure to perform can be reasonably expected to  
cause the failure of the life support device or system, or to affect its  
safety or effectiveness.  
ANTI-COUNTERFEITING POLICY  
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,  
under Sales Support.  
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their  
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed  
applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the  
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild  
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors  
are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical  
and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.  
Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global  
problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
