3 Description
The LM340 and LM78xx monolithic 3-terminal
positive voltage regulators employ internal current-
limiting, thermal shutdown and safe-area
compensation, making them essentially indestructible.
If adequate heat sinking is provided, they can deliver
over 1.5-A output current. They are intended as fixed
voltage regulators in a wide range of applications
including local (on-card) regulation for elimination of
noise and distribution problems associated with
single-point regulation. In addition to use as fixed
voltage regulators, these devices can be used with
external components to obtain adjustable output
voltages and currents.
Considerable effort was expended to make the entire
series of regulators easy to use and minimize the
number of external components. It is not necessary to
bypass the output, although this does improve
transient response. Input bypassing is needed only if
the regulator is located far from the filter capacitor of
the power supply.
LM7805 is also available in a higher accuracy and
better performance version (LM340A). Refer to
LM340A specifications in the LM340A Electrical
Characterisitcs table.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The maximum allowable power dissipation at any ambient temperature is a function of the maximum junction temperature for operation
(TJMAX = 125°C or 150°C), the junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA). PDMAX = (TJMAX
TA)/θJA. If this dissipation is exceeded, the die temperature rises above TJMAX and the electrical specifications do not apply. If the die
temperature rises above 150°C, the device goes into thermal shutdown. For the TO-3 package (NDS), the junction-to-ambient thermal
resistance (θJA) is 39°C/W. When using a heat sink, θJA is the sum of the 4°C/W junction-to-case thermal resistance (θJC) of the TO-3
package and the case-to-ambient thermal resistance of the heat sink. For the TO-220 package (NDE), θJA is 54°C/W and θJC is 4°C/W.
If SOT-223 is used, the junction-to-ambient thermal resistance is 174°C/W and can be reduced by a heat sink (see Applications Hints on
heat sinking).If the DDPAK\TO-263 package is used, the thermal resistance can be reduced by increasing the PCB copper area
thermally connected to the package: Using 0.5 square inches of copper area, θJA is 50°C/W; with 1 square inch of copper area, θJA is
37°C/W; and with 1.6 or more inches of copper area, θJA is 32°C/W.

7 Detailed Description
7.1 Overview
The LM340 and LM78xx are a family of fixed output positive voltage regulators with outputs ranging from 3 V to
15 V. They accept up to 35 V of input voltage and with proper heat dissipation can provide over 1.5 A of current.
With a combination of current limiting, thermal shutdown, and safe area protection, these regulators eliminate
any concern of damage. These features paired with excellent line and load regulation make the LM340 and
LM78xx versatile solutions to a wide range of power management designs. Although the LM340N and LM78xx
were designed primarily as fixed-voltage regulators, these devices can be used with external component for
adjustable voltage and current.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Output Current
With proper considerations, the LM340 and LM78xx can exceed 1.5-A output current. Depending on the desired
package option, the effective junction-to-ambient thermal resistance can be reduced through heat sinking,
allowing more power to be dissipated in the device.
7.3.2 Current Limiting Feature
In the event of a short circuit at the output of the regulator, each device has an internal current limit to protect it
from damage. The typical current limits for the LM340 and LM78xx is 2.4 A.
7.3.3 Thermal Shutdown
Each package type employs internal current limiting and thermal shutdown to provide safe operation area
protection. If the junction temperature is allowed to rise to 150°C, the device will go into thermal shutdown.
7.4 Device Functional Modes
There are no functional modes for this device.

Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LM340x and LM78xx series is designed with thermal protection, output short-circuit protection, and output
transistor safe area protection. However, as with any IC regulator, it becomes necessary to take precautions to
assure that the regulator is not inadvertently damaged. The following describes possible misapplications and
methods to prevent damage to the regulator.
8.1.1 Shorting the Regulator Input
When using large capacitors at the output of these regulators, a protection diode connected input to output
(Figure 15) may be required if the input is shorted to ground. Without the protection diode, an input short causes
the input to rapidly approach ground potential, while the output remains near the initial VOUT because of the
stored charge in the large output capacitor. The capacitor will then discharge through a large internal input to
output diode and parasitic transistors. If the energy released by the capacitor is large enough, this diode, low
current metal, and the regulator are destroyed. The fast diode in Figure 15 shunts most of the capacitors
discharge current around the regulator. Generally no protection diode is required for values of output capacitance
10 μF.
8.1.2 Raising the Output Voltage Above the Input Voltage
Because the output of the device does not sink current, forcing the output high can cause damage to internal low
current paths in a manner similar to that just described in Shorting the Regulator Input.
8.1.3 Regulator Floating Ground
When the ground pin alone becomes disconnected, the output approaches the unregulated input, causing
possible damage to other circuits connected to VOUT. If ground is reconnected with power ON, damage may also
occur to the regulator. This fault is most likely to occur when plugging in regulators or modules with on card
regulators into powered up sockets. The power must be turned off first, the thermal limit ceases operating, or the
ground must be connected first if power must be left on. See Figure 16.
8.1.4 Transient Voltages
If transients exceed the maximum rated input voltage of the device, or reach more than 0.8 V below ground and
have sufficient energy, they will damage the regulator. The solution is to use a large input capacitor, a series
input breakdown diode, a choke, a transient suppressor or a combination of these.

Figure 16. Regulator Floating Ground
Figure 17. Transients
When a value for θ(H–A) is found, a heat sink must be selected that has a value that is less than or equal to this
number.
θ(H–A) is specified numerically by the heat sink manufacturer in this catalog or shown in a curve that plots
temperature rise vs power dissipation for the heat sink.
8.2 Typical Applications
8.2.1 Fixed Output Voltage Regulator
The LM340x and LM78xx devices are primarily designed to provide fixed output voltage regulation. The simplest
implementation of LM340x and LM78xx is shown in Figure 18.
*Required if the regulator is located far from the power supply filter.
**Although no output capacitor is needed for stability, it does help transient response. (If needed, use 0.1-μF, ceramic
disc).
Figure 18. Fixed Output Voltage Regulator
8.2.1.1 Design Requirements
The device component count is very minimal. Although not required, TI recommends employing bypass
capacitors at the output for optimum stability and transient response. These capacitors must be placed as close
as possible to the regulator. If the device is located more than 6 inches from the power supply filter, it is required
to employ input capacitor.

9 Power Supply Recommendations
The LM340 is designed to operate from a wide input voltage up to 35 V. Please refer to electrical characteristics
tables for the minimum input voltage required for line/load regulation. If the device is more than six inches from
the input filter capacitors, an input bypass capacitor, 0.1 μF or greater, of any type is needed for stability.
10 Layout
10.1 Layout Guidelines
Some layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise.
Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance. To improve
PSRR, a bypass capacitor can be placed at the OUTPUT pin and must be placed as close as possible to the IC.
All that is required for the typical fixed output regulator application circuit is the LM340x/LM78xx IC and a 0.22-µF
input capacitor if the regulator is placed far from the power supply filter. A 0.1-µF output capacitor is
recommended to help with transient response. In cases when VIN shorts to ground, an external diode must be
placed from VOUT to VIN to divert the surge current from the output capacitor and protect the IC.

10.3 Heat Sinking DDPAK/TO-263 and SOT-223 Package Parts
Both the DDPAK/TO-263 (KTT) and SOT-223 (DCY) packages use a copper plane on the PCB and the PCB
itself as a heat sink. To optimize the heat sinking ability of the plane and PCB, solder the tab of the plane.
Figure 29 shows for the DDPAK/TO-263 the measured values of θ(J–A) for different copper area sizes using a
typical PCB with 1-oz copper and no solder mask over the copper area used for heat sinking.

Heat Sinking DDPAK/TO-263 and SOT-223 Package Parts (continued)
As shown in Figure 29, increasing the copper area beyond 1 square inch produces very little improvement. It
should also be observed that the minimum value of θ(J–A) for the DDPAK/TO-263 package mounted to a PCB is
32°C/W.
As a design aid, Figure 30 shows the maximum allowable power dissipation compared to ambient temperature
for the DDPAK/TO-263 device (assuming θ(J–A) is 35°C/W and the maximum junction temperature is 125°C).
Figure 30. Maximum Power Dissipation vs TAMB for the DDPAK/TO-263 Package
Figure 31 and Figure 32 show the information for the SOT-223 package. Figure 31 assumes a θ(J–A) of 74°C/W
for 1-oz. copper and 51°C/W for 2-oz. copper and a maximum junction temperature of 125°C.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
