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. 1 • • • • • Output Current up to 1.5 A Available in Fixed 5-V, 12-V, and 15-V Options Output Voltage Tolerances of ±2% at TJ = 25°C (LM340A) Line Regulation of 0.01% / V of at 1-A Load (LM340A) Load Regulation of 0.3% / A (LM340A) Internal Thermal Overload, Short-Circuit and SOA Protection Available in Space-Saving SOT-223 Package Output Capacitance Not Required for Stability 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. 2 Applications • • • • Industrial Power Supplies SMPS Post Regulation HVAC Systems White Goods SPACE LM7805 is also available in a higher accuracy and better performance version (LM340A).

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. If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. 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. 6.2 ESD Ratings V(ESD) (1) Electrostatic discharge Human-body model (HBM) (1) VALUE UNIT ±2000 V ESD rating is based on the human-body model, 100 pF discharged through 1.5 kΩ. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) Temperature (TA) MIN MAX UNIT 0 125 °C LM340A, LM340 6.4 Thermal Information LM340, LM78xx THERMAL METRIC (1) RθJA KTT (DDPAK/TO-263) DCY (SOT-223) NDS (TO-3) 3 PINS 3 PINS 4 PINS 2 PINS UNIT 23.9 44.8 62.1 39 °C/W RθJC(top) Junction-to-case (top) thermal resistance 16.7 45.6 44 2 °C/W RθJB Junction-to-board thermal resistance 5.3 24.4 10.7 — °C/W ψJT Junction-to-top characterization parameter 3.2 11.2 2.7 — °C/W ψJB Junction-to-board characterization parameter 5.3 23.4 10.6 — °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 1.7 1.5 — — °C/W (1) 4 Junction-to-ambient thermal resistance NDE (TO-220) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report.

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. 12 Submit Documentation Feedback Copyright © 2000–2016, Texas Instruments Incorporated Product Folder Links: LM340 LM340A LM7805 LM7812 LM7815 LM340, LM340A, LM7805, LM7812, LM7815 www.ti.com SNOSBT0K – FEBRUARY 2000 – REVISED JULY 2016 8 Application and Implementation NOTE 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 15.

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. 14 Submit Documentation Feedback Copyright © 2000–2016, Texas Instruments Incorporated Product Folder Links: LM340 LM340A LM7805 LM7812 LM7815 LM340, LM340A, LM7805, LM7812, LM7815 www.ti.com SNOSBT0K – FEBRUARY 2000 – REVISED JULY 2016 Typical Applications (continued) 8.2.1.2 Detailed Design Procedure The output voltage is set based on the device variant.

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. 10.2 Layout Example Figure 27.

Layout Example SOT-223 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. Figure 29. θ(J–A) vs Copper (1 Ounce) Area for the DDPAK/TO-263 Package 18 Submit Documentation Feedback Copyright © 2000–2016, Texas Instruments Incorporated Product Folder Links: LM340 LM340A LM7805 LM7812 LM7815 LM340, LM340A, LM7805, LM7812, LM7815 www.ti.com SNOSBT0K – FEBRUARY 2000 – REVISED JULY 2016 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.
