KA78XXE/KA78XXAE
3-Terminal 1A Positive Voltage Regulator
Features
General Description
• Output Current up to 1A
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 use-
ful in a wide range of applications. Each type employs
internal current limiting, thermal shut down and safe oper-
ating 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 exter-
nal components to obtain adjustable voltages and cur-
rents.
• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V
• Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe Operating Area Protection

Notes:
1. 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 2.0V above the output voltage even during the low point
on the input ripple voltage.
2. C is required if regulator is located an appreciable distance from power Supply filter.

DISCLAIMER
FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE
RELIABILITY, FUNCTION, OR DESIGN. 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.
