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. 8.2 Functional Block Diagram Submit Documentation Feedback Copyright © 2004–2020, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 9 LM341, LM78M05 SNVS090G – MAY 2004 – REVISED JUNE 2020 www.ti.com 8.3 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 125°C 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. 8.4 Device Functional Modes 8.4.1 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. 8.4.2 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. 8.4.3 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 © 2004–2020, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 LM341, LM78M05 www.ti.com SNVS090G – MAY 2004 – REVISED JUNE 2020 9 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. 9.1 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. 9.2 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 9.2.1 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 µF COUT 0.1 µF 9.2.2 Detailed Design Procedure 9.2.2.1 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). 9.2.2.2 Output Current Depending on the input-output voltage differential, the output current must be limited to ensure maximum power dissipation is not exceeded. The graph in Figure 1 shows the appropriate current limit for a variety of conditions. 9.2.2.3 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.

However if large changes in load are expected, an output capacitor is recommended to improve the transient response. 9.2.3 Application Curves Figure 12. RθJA 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 10 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-µF or greater of any type is recommended. 11 Layout 11.1 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. 12 Submit Documentation Feedback Copyright © 2004–2020, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 LM341, LM78M05 www.ti.com SNVS090G – MAY 2004 – REVISED JUNE 2020 Layout Guidelines (continued) 11.1.1 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 15. 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 (RθJC) • Leadframe size and material • Number of conduction pins • Die size • Die attach material • Molding compound size and material Application variables (RθCA) • 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 The case temperature is measured at the point where the leads contact the mounting pad surface Figure 15. 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 0°C to 125°C. 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) × IL + (VIN × IG) (1) (2) Submit Documentation Feedback Copyright © 2004–2020, Texas Instruments Incorporated Product Folder Links: LM341 LM78M05 13 LM341, LM78M05 SNVS090G – MAY 2004 – REVISED JUNE 2020 www.ti.com Layout Guidelines (continued) Figure 16 shows the voltages and currents which are present in the circuit. Figure 16. 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 (125°C) 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 (RθJA) can be calculated with Equation 3. RθJA = TR(MAX) / PD (3) As a design aid, Table 2 lists the value of the RθJA of TO-252 for different heat sink area. The copper patterns that we used to measure these RθJA are shown at the end of the AN–1028 Maximum Power Enhancement Techniques for Power Packages application note. Figure 12 reflects the same test results as what are in the Table 2. Figure 13 illustrates the maximum allowable power dissipation versus ambient temperature for the PFM device. Figure 14 illustrates the maximum allowable power dissipation versus copper area (in2) for the TO-252 device.
