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

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.

Typical Application
Design Considerations
The KA79L05A fixed voltage-regulator is designed with thermal overload protection that shuts down the circuit when
subjected to an excessive power overload condition. Internal short-circuit protection limits the maximum current the cir-
cuit will pass. In many low current applications, compensation capacitors are not required. However, it is recommended
that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long
wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good
high-frequency characteristics to ensure stable operation under all load conditions. A 0.33 μF or larger tantalum, mylar,
or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should
be mounted with the shortest possible leads directly across the regulator's input terminals. Good construction tech-
niques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense
lead. Bypassing the output is also recommended.

Figure 3. Typical Application
Figure 2. Positive and Negative Regulator
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V
above the output voltage, even during the low point on the input ripple voltage.
* CI is required if regulator is located an appreciable distance from power supply filter.
** CO improves stability and transient response.

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.

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.
