8 Detailed Description
8.1 Overview
The LM341 and LM78M05 devices are a family of fixed positive voltage regulators. 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.

8.3 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.

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.

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.

9.2.2.4 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.

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.

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

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)

Figure 16 shows the voltages and currents which are present in the circuit.

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

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.
For power enhancement techniques to be used with TO-252 package, see the AN–1028 Maximum Power
Enhancement Techniques for Power Packages application note.
