APPLICATION NOTE  
GENERAL  
Figure 18 shows a basic functional diagram for the LM1086-Adj (excluding protection circuitry) . The topology is  
basically that of the LM317 except for the pass transistor. Instead of a Darlingtion NPN with its two diode voltage  
drop, the LM1086 uses a single NPN. This results in a lower dropout voltage. The structure of the pass transistor  
is also known as a quasi LDO. The advantage a quasi LDO over a PNP LDO is its inherently lower quiescent  
current. The LM1086 is specified to provide a minimum dropout voltage 1.5V over temperature, at full load.  
Figure 18. Basic Functional Diagram for the LM1086, excluding Protection circuitry  
OUTPUT VOLTAGE  
The LM1086 adjustable version develops at 1.25V reference voltage, (VREF), between the output and the adjust  
terminal. As shown in figure 2, this voltage is applied across resistor R1 to generate a constant current I1. This  
constant current then flows through R2. The resulting voltage drop across R2 adds to the reference voltage to  
sets the desired output voltage.  
The current IADJ from the adjustment terminal introduces an output error . But since it is small (120uA max), it  
becomes negligible when R1 is in the 100range.  
For fixed voltage devices, R1 and R2 are integrated inside the devices.  
Figure 19. Basic Adjustable Regulator  
STABILITY CONSIDERATION  
Stability consideration primarily concern the phase response of the feedback loop. In order for stable operation,  
the loop must maintain negative feedback. The LM1086 requires a certain amount series resistance with  
capacitive loads. This series resistance introduces a zero within the loop to increase phase margin and thus  
increase stability. The equivalent series resistance (ESR) of solid tantalum or aluminum electrolytic capacitors is  
used to provide the appropriate zero (approximately 500 kHz).

SNVS039H JUNE 2000REVISED MAY 2013  
The Aluminum electrolytic are less expensive than tantalums, but their ESR varies exponentially at cold  
temperatures; therefore requiring close examination when choosing the desired transient response over  
temperature. Tantalums are a convenient choice because their ESR varies less than 2:1 over temperature.  
The recommended load/decoupling capacitance is a 10uF tantalum or a 50uF aluminum. These values will  
assure stability for the majority of applications.  
The adjustable versions allows an additional capacitor to be used at the ADJ pin to increase ripple rejection. If  
this is done the output capacitor should be increased to 22uF for tantalums or to 150uF for aluminum.  
Capacitors other than tantalum or aluminum can be used at the adjust pin and the input pin. A 10uF capacitor is  
a reasonable value at the input. See RIPPLE REJECTION section regarding the value for the adjust pin  
capacitor.  
It is desirable to have large output capacitance for applications that entail large changes in load current  
(microprocessors for example). The higher the capacitance, the larger the available charge per demand. It is also  
desirable to provide low ESR to reduce the change in output voltage:  
ΔV = ΔI x ESR  
It is common practice to use several tantalum and ceramic capacitors in parallel to reduce this change in the  
output voltage by reducing the overall ESR.  
Output capacitance can be increased indefinitely to improve transient response and stability.  
RIPPLE REJECTION  
Ripple rejection is a function of the open loop gain within the feed-back loop (refer to Figure 18 and Figure 19).  
The LM1086 exhibits 75dB of ripple rejection (typ.). When adjusted for voltages higher than VREF, the ripple  
rejection decreases as function of adjustment gain: (1+R1/R2) or VO/VREF. Therefore a 5V adjustment decreases  
ripple rejection by a factor of four (12dB); Output ripple increases as adjustment voltage increases.  
However, the adjustable version allows this degradation of ripple rejection to be compensated. The adjust  
terminal can be bypassed to ground with a capacitor (CADJ). The impedance of the CADJ should be equal to or  
less than R1 at the desired ripple frequency. This bypass capacitor prevents ripple from being amplified as the  
output voltage is increased.  
1/(2π*fRIPPLE*CADJ) R1  
LOAD REGULATION  
The LM1086 regulates the voltage that appears between its output and ground pins, or between its output and  
adjust pins. In some cases, line resistances can introduce errors to the voltage across the load. To obtain the  
best load regulation, a few precautions are needed.  
Figure 20 shows a typical application using a fixed output regulator. Rt1 and Rt2 are the line resistances. VLOAD  
is less than the VOUT by the sum of the voltage drops along the line resistances. In this case, the load regulation  
seen at the RLOAD would be degraded from the data sheet specification. To improve this, the load should be tied  
directly to the output terminal on the positive side and directly tied to the ground terminal on the negative side.

When the adjustable regulator is used (Figure 21), the best performance is obtained with the positive side of the  
resistor R1 tied directly to the output terminal of the regulator rather than near the load. This eliminates line drops  
from appearing effectively in series with the reference and degrading regulation. For example, a 5V regulator with  
0.05resistance between the regulator and load will have a load regulation due to line resistance of 0.05x IL.  
If R1 (=125) is connected near the load the effective line resistance will be 0.05(1 + R2/R1) or in this case, it  
is 4 times worse. In addition, the ground side of the resistor R2 can be returned near the ground of the load to  
provide remote ground sensing and improve load regulation.  
Figure 21. Best Load Regulation using Adjustable Output Regulator  
PROTECTION DIODES  
Under normal operation, the LM1086 regulator does not need any protection diode. With the adjustable device,  
the internal resistance between the adjustment and output terminals limits the current. No diode is needed to  
divert the current around the regulator even with a capacitor on the adjustment terminal. The adjust pin can take  
a transient signal of ±25V with respect to the output voltage without damaging the device.  
When an output capacitor is connected to a regulator and the input is shorted, the output capacitor will discharge  
into the output of the regulator. The discharge current depends on the value of the capacitor, the output voltage  
of the regulator, and rate of decrease of VIN. In the LM1086 regulator, the internal diode between the output and  
input pins can withstand microsecond surge currents of 10A to 20A. With an extremely large output capacitor  
(1000 µf), and with input instantaneously shorted to ground, the regulator could be damaged. In this case, an  
external diode is recommended between the output and input pins to protect the regulator, shown in Figure 22.

OVERLOAD RECOVERY  
Overload recovery refers to regulator's ability to recover from a short circuited output. A key factor in the recovery  
process is the current limiting used to protect the output from drawing too much power. The current limiting circuit  
reduces the output current as the input to output differential increases. Refer to short circuit curve in the Typical  
Performance Characteristics section.  
During normal start-up, the input to output differential is small since the output follows the input. But, if the output  
is shorted, then the recovery involves a large input to output differential. Sometimes during this condition the  
current limiting circuit is slow in recovering. If the limited current is too low to develop a voltage at the output, the  
voltage will stabilize at a lower level. Under these conditions it may be necessary to recycle the power of the  
regulator in order to get the smaller differential voltage and thus adequate start up conditions. Refer to Typical  
Performance Characteristics section for the short circuit current vs. input differential voltage.  
THERMAL CONSIDERATIONS  
ICs heats up when in operation, and power consumption is one factor in how hot it gets. The other factor is how  
well the heat is dissipated. Heat dissipation is predictable by knowing the thermal resistance between the IC and  
ambient (θJA). Thermal resistance has units of temperature per power (C/W). The higher the thermal resistance,  
the hotter the IC.  
The LM1086 specifies the thermal resistance for each package as junction to case (θJC). In order to get the total  
resistance to ambient (θJA), two other thermal resistance must be added, one for case to heat-sink (θCH) and one  
for heatsink to ambient (θHA). The junction temperature can be predicted as follows:  
TJ = TA + PD (θJC + θCH + θHA) = TA + PD θJA  
where  
TJ is junction temperature  
TA is ambient temperature  
PD is the power consumption of the device  
Device power consumption is calculated as follows:  
IIN = IL + IG  
PD = (VINVOUT) IL + VINIG  
Figure 23 shows the voltages and currents which are present in the circuit.  
Figure 23. Power Dissipation Diagram  
Once the device power is determined, the maximum allowable (θJA(max)) is calculated as:  
θJA (max) = TR(max)/PD = TJ(max) TA(max))/PD  
The LM1086 has different temperature specifications for two different sections of the IC: the control section and  
the output section. The Electrical Characteristics table shows the junction to case thermal resistances for each of  
these sections, while the maximum junction temperatures (TJ(max)) for each section is listed in the Absolute  
Maximum section of the datasheet. TJ(max) is 125°C for the control section, while TJ(max) is 150°C for the output  
section.  
θJA (max) should be calculated separately for each section as follows:  
θJA (max, CONTROL SECTION) = (125°C for TA(max))/PD  
θJA (max, OUTPUT SECTION) = (150°C for TA(max))/PD

The required heat sink is determined by calculating its required thermal resistance (θHA(max)).  
θHA(max) = θJA(max) (θJC + θCH  
)
θHA (max) should be calculated twice as follows:  
θHA (max) = θJA(max, CONTROL SECTION) - (θJC (CONTROL SECTION) + θCH  
)
θHA (max)= θJA(max, OUTPUT SECTION) - (θJC(OUTPUT SECTION) + θCH  
)
If thermal compound is used, θCH can be estimated at 0.2 C/W. If the case is soldered to the heat sink, then a  
θCH can be estimated as 0 C/W.  
After, θHA  
is calculated for each section, choose the lower of the two θHA  
values to determine the  
(max)  
(max)  
appropriate heat sink.  
If PC board copper is going to be used as a heat sink, then Figure 24 can be used to determine the appropriate  
area (size) of copper foil required.

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.
