They can accept up to 35 V at the input and regulate it down to outputs of 5 V, 12 V, or 15 V. The devices are capable of supplying up to 500 mA of output current, although it is important to ensure there is adequate heat sinking to avoid exceeding thermal limits. However, in the case of accidental overload the device has built in current limiting, thermal shutdown and safe-operating area protection to prevent damage from occurring. 8 Submit Documentation Feedback Copyright (c) 2004-2016, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 LM341, LM78M05 www.ti.com SNVS090F - MAY 2004 - REVISED DECEMBER 2016 7.2 Functional Block Diagram Submit Documentation Feedback Copyright (c) 2004-2016, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 9 LM341, LM78M05 SNVS090F - MAY 2004 - REVISED DECEMBER 2016 www.ti.com 7.3 Feature Description The LM341 and LM78M05 fixed voltage regulators have built-in thermal overload protection which prevents the device from being damaged due to excessive junction temperature. The regulators also contain internal short-circuit protection which limits the maximum output current, and safearea protection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is increased. Although the internal power dissipation is automatically limited, the maximum junction temperature of the device must be kept below 125C to meet data sheet specifications. An adequate heat sink must be provided to assure this limit is not exceeded under worst-case operating conditions (maximum input voltage and load current) if reliable performance is to be obtained. 7.4 Device Functional Modes 7.4.1 Normal Operation The device OUTPUT pin sources current necessary to make the voltage at the OUTPUT pin equal to the fixed voltage level of the device. 7.4.2 Operation With Low Input Voltage The device requires up to 2-V headroom (VI - VO) to operate in regulation. With less headroom, the device may drop out of regulation in which the OUTPUT voltage would equal INPUT voltage minus dropout voltage. 7.4.3 Operation in Self Protection When an overload occurs, the device shuts down Darlington NPN output stage or reduce the output current to prevent device damage. The device automatically resets from the overload. The output may be reduced or alternate between on and off until the overload is removed. 10 Submit Documentation Feedback Copyright (c) 2004-2016, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 LM341, LM78M05 www.ti.com SNVS090F - MAY 2004 - REVISED DECEMBER 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 LM341 and LM78Mxx devices are fixed voltage regulators meaning no external feedback resistors are required to set the output voltage. Input and output capacitors are also not required for the device to be stable. However input capacitance helps filter noise from the supply and output capacitance improves the transient response. 8.2 Typical Application *Required if regulator input is more than 4 inches from input filter capacitor (or if no input filter capacitor is used). **Optional for improved transient response. Figure 11. Typical Application 8.2.1 Design Requirements For this design example, use the parameters listed in Table 1 as the input parameters. Table 1. Design Parameters PARAMETER VALUE CIN 0.33 F COUT 0.1 F 8.2.2 Detailed Design Procedure 8.2.2.1 Input Voltage Regardless of the output voltage option being used (5 V, 12 V, 15 V), the input voltage must be at least 2 V greater to ensure proper regulation (7 V, 14 V, 17 V).

The graph in Figure 1 shows the appropriate current limit for a variety of conditions. 8.2.2.3 Input Capacitor If no power supply filter capacitor is used or if the device is placed more than four inches away from the capacitor of the power supply, an additional capacitor placed at the input pin of the device helps bypass noise. 8.2.2.4 Output Capacitor These devices are designed to be stable with no output capacitance and can be omitted from the design if needed. However if large changes in load are expected, an output capacitor is recommended to improve the transient response. 8.2.3 Application Curves Figure 12. RJA vs 2-oz Copper Area for PFM Figure 13. Maximum Allowable Power Dissipation vs Ambient Temperature for PFM Figure 14. Maximum Allowable Power Dissipation vs 2-oz Copper Area for PFM 9 Power Supply Recommendations The LM341 and LM78M05 devices are designed to operate from an input voltage supply range between VOUT + 2 V to 35 V. If the device is more than four inches from the power supply filter capacitors, an input bypass capacitor 0.1-F or greater of any type is recommended. 12 Submit Documentation Feedback Copyright (c) 2004-2016, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 LM341, LM78M05 www.ti.com SNVS090F - MAY 2004 - REVISED DECEMBER 2016 10 Layout 10.1 Layout Guidelines Some layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise. TI recommends that the input terminal be bypassed to ground with a bypass capacitor. The optimum placement is closest to the input terminal of the device and the system GND. Take care to minimize the loop area formed by the bypass-capacitor connection, the input terminal, and the system GND. Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance. 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. This diode must be placed close to the corresponding IC pins to increase their effectiveness. 10.2 Layout Example Figure 15. Layout Recommendation 10.3 Thermal Considerations When an integrated circuit operates with appreciable current, its junction temperature is elevated. It is important to quantify its thermal limits to achieve acceptable performance and reliability. This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating environment. A one-dimension steady-state model of conduction heat transfer is demonstrated in Figure 16. The heat generated at the device junction flows through the die to the die attach pad, through the lead frame to the surrounding case material, to the printed-circuit board, and eventually to the ambient environment. There are several variables that may affect the thermal resistance and in turn the need for a heat sink, which includes the following. Component variables (RJC) * Leadframe size and material * Number of conduction pins * Die size * Die attach material * Molding compound size and material Application variables (RCA) * Mounting pad size, material, and location * Placement of mounting pad * PCB size and material * Traces length and width * Adjacent heat sources * Volume of air * Ambient temperature * Shape of mounting pad Submit Documentation Feedback Copyright (c) 2004-2016, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 13 LM341, LM78M05 SNVS090F - MAY 2004 - REVISED DECEMBER 2016 www.ti.com Thermal Considerations (continued) The case temperature is measured at the point where the leads contact the mounting pad surface Figure 16. Cross-Sectional View of Integrated Circuit Mounted on a Printed-Circuit Board The LM341 and LM78M05 regulators have internal thermal shutdown to protect the device from overheating. Under all possible operating conditions, the junction temperature of the LM341 and LM78M05 must be within the range of 0C to 125C. A heat sink may be required depending on the maximum power dissipation and maximum ambient temperature of the application. To determine if a heat sink is needed, the power dissipated by the regulator (PD) is calculated using Equation 1. IIN = IL + IG PD = (VIN - VOUT) x IL + (VIN x IG) (1) (2) Figure 17 shows the voltages and currents which are present in the circuit. Figure 17. Power Dissipation Diagram The next parameter which must be calculated is the maximum allowable temperature rise, TR(MAX). TR(MAX) = TJ(MAX) - TA(MAX) where * * TJ(MAX) is the maximum allowable junction temperature (125C) TA(MAX) is the maximum ambient temperature encountered in the application Using the calculated values for TR(MAX) and PD, the maximum allowable value for the junction-to-ambient thermal resistance (RJA) can be calculated with Equation 3. RJA = TR(MAX) / PD (3) As a design aid, Table 2 shows the value of the RJA of TO-252 for different heat sink area. The copper patterns that we used to measure these RJA are shown at the end of AN-1028 Maximum Power Enhancement Techniques for Power Packages (SNVA036). Figure 12 reflects the same test results as what are in the Table 2. Figure 13 shows the maximum allowable power dissipation versus ambient temperature for the PFM device. Figure 14 shows the maximum allowable power dissipation versus copper area (in2) for the TO-252 device.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. TI's published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and services. Reproduction of significant portions of TI information in TI 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 reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyers and others who are developing systems that incorporate TI products (collectively, "Designers") understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers' applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI's provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, "TI Resources") are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer's company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI's provision of TI Resources does not expand or otherwise alter TI's applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. Use of TI Resources 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. TI RESOURCES ARE PROVIDED "AS IS" AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM, INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL, DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers' own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer's noncompliance with the terms and provisions of this Notice.
