LM2936 Ultra-Low Quiescent Current LDO Voltage Regulator
1 Features
3 Description
•
•
•
The LM2936 ultra-low quiescent current regulator
features low dropout voltage and low current in the
standby mode. With less than 15-μA quiescent
current at a 100-μA load, the LM2936 is ideally suited
for automotive and other battery operated systems.
The LM2936 retains all of the features that are
common to low dropout regulators including a low
dropout PNP pass device, short circuit protection,
reverse battery protection, and thermal shutdown.
The LM2936 has a 40-V maximum operating voltage
limit, a −40°C to 125°C operating temperature range,
and ±3% output voltage tolerance over the entire
output current, input voltage, and temperature range.
The LM2936 is available in a TO-92 through-hole
package, as well as SOIC-8, VSSOP, SOT–223, and
TO-252 surface mount packages.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its specified operating ratings.
If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(MAX) − TA) / RθJA. If this dissipation is exceeded, the die temperature can rise above the TJ(MAX) of 150°C, and
the LM2936 may go into thermal shutdown.

7.1 Overview
The LM2936 ultra-low quiescent current regulator features low dropout voltage and low current in the standby
mode. With less than 15 μA quiescent current at a 100-μA load, the LM2936 is ideally suited for automotive and
other battery operated systems. The LM2936 retains all of the features that are common to low dropout
regulators including a low dropout PNP pass device, short circuit protection, reverse battery input protection, and
thermal shutdown. The LM2936 has a 40-V maximum operating voltage limit, a −40°C to 125°C operating
temperature range, and ±3% output voltage tolerance over the entire output current, input voltage, and
temperature range.

7.3 Feature Description
7.3.1 High Input Operating Voltage
Unlike namy other PNP low dropout regulators, the LM2936 remains fully operational with VIN = 40 V, and the
LM2936HV remains fully operational with VIN = 60 V . Owing to power dissipation characteristics of the available
packages, full output current cannot be ensured for all combinations of ambient temperature and input voltage.
While the LM2936HV maintains regulation to 60 V, it will not withstand a short circuit to ground on the output
when VIN is above 40 V because of safe operating area limitations in the internal PNP pass device. Above 60V
the LM2936 will break down with catastrophic effects on the regulator and possibly the load as well. Do not use
this device in a design where the input operating voltage may exceed 40 V, or where transients are likely to
exceed 60 V.
7.3.2 Thermal Shutdown (TSD)
The TSD circuitry of the LM2936 has been designed to protect the device against temporary thermal overload
conditions. The TSD circuitry is not intended to replace proper heat-sinking. Continuously running the LM2936
device at TSD may degrade device reliability as the junction temperature will be exceeding the absolute
maximum junction temperature rating. If the LM2936 goes into TSD mode, the output current will be shut off until
the junction temperature falls approximately 10°C, then the output current will automatically be restored. The
LM2936 will continuously cycle in and out of TSD until the condition is corrected. The LM2936 TSD junction
temperature is typically 160°C.

Feature Description (continued)
7.3.3 Short-Circuit Current Limit
The output current limiting circuitry of the LM2936 has been designed to limit the output current in cases where
the load impedance is unusually low. This includes situations where the output may be shorted directly to ground.
Continuous operation of the LM2936 at the current limit will typically result in the LM2936 transitioning into TSD
mode.
7.3.4 Shutdown (SD) Pin
The LM2936BM has a pin for shutting down the regulator output. Applying a Logic Level High (> 2 V) to the SD
pin will cause the output to turn off. Leaving the SD pin open, connecting it to Ground, or applying a Logic Level
Low (< 0.6 V) will allow the regulator output to turn on.
7.4 Device Functional Modes
The LM2936 design does not include any undervoltage lockout (UVLO), or overvoltage shutdown (OVSD)
functions. Generally, the output voltage will track the input voltage until the input voltage is greater than VOUT + 1
V. When the input voltage is greater than VOUT + 1 V the LM2936 will be in linear operation, and the output
voltage will be regulated; however, the device will be sensitive to any small perturbation of the input voltage.
Device dynamic performance is improved when the input voltage is at least 2 V greater than the output voltage.

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 LM2936 ultra-low quiescent current regulator features low dropout voltage and low current in the standby
mode. The LM2936 has a 40-V maximum operating voltage limit, a −40°C to 125°C operating temperature range,
–24-V input voltage protection and ±3% output voltage tolerance over the entire output current, input voltage, and
temperature range This following section presents a simplified discussion of the design process. Also the
WEBENCH® software may be used to generate complete designs. When generating a design, WEBENCH
utilizes iterative design procedure and accesses comprehensive databases of components. Please go to
www.ti.com for more details.
8.2 Typical Application
Figure 21 shows the typical application circuit for the LM2936. For the LM2936 5-V option, the output capacitor,
COUT, must have a capacitance value of at least 10 µF with an equivalent series resistance (ESR) of at least 300
mΩ, but no more than 8 Ω. For the LM2936 3.3-V and 3-V options, the output capacitor, COUT, must have a
capacitance value of at least 22 µF with an ESR of at least 300 mΩ, but no more than 8 Ω. The minimum
capacitance value and the ESR requirements apply across the entire expected operating ambient temperature
range.

8.2.2 Detailed Design Procedure
8.2.2.1 External Capacitors
The output capacitor is critical to maintaining regulator stability, and must meet the required conditions for both
ESR and minimum amount of capacitance.
8.2.2.1.1 Minimum Capacitance
The minimum output capacitance required to maintain stability is at least 10 µF for the LM2936 5-V option, and
at least 22 µF for the 3.3-V and 3-V options. This value may be increased without limit. Larger values of output
capacitance will give improved transient response.
8.2.2.1.2 ESR Limits
The ESR of the output capacitor will cause loop instability if it is too high, or too low. ESR, of the COUT capacitor
must at least 300 mΩ, but no more than 8 Ω.
8.2.2.2 Output Capacitor ESR
It is essential that the output capacitor meet the capacitance and ESR requirements, or oscillations can result.
The ESR is used with the output capacitance in
Ceramic capacitors (MLCC) can be used for COUT only if a series resistor is added to simulate the ESR
requirement. The ESR is not optional, it is mandatory. Typically, a 500-mΩ to 1-Ω series resistor is used for this
purpose. When using ceramic capacitors, due diligence must be given to initial tolerances, capacitance derating
due to applied DC voltage, and capacitance variations due to temperature. Dielectric types X5R and X7R are
preferred.
8.2.3 Application Curve

9 Power Supply Recommendations
This device is designed to operate from an input supply voltage from at least VOUT + 1 V up to a maximum of 40
V. The input supply should be well regulated and free of spurious noise. To ensure that the LM2936 output
voltage is well regulated the input supply should be at least VOUT + 2 V. A capacitor at the IN pin may not be
specifically required if the bulk input supply filter capacitors are within three inches of the IN pin, but adding one
will not be detrimental to operation.
While the LM2936 maintains regulation to VIN = 60 V, it will not withstand a short circuit on the output with VIN
above 40 V because of safe operating area limitations in the internal PNP pass device. With VIN above 60 V the
LM2936 will break down with catastrophic effects on the regulator and possibly the load as well. Do not use this
device in a design where the input operating voltage, including transients, is likely to exceed 60 V.

10 Layout
10.1 Layout Guidelines
The dynamic performance of the LM2936 is dependent on the layout of the PCB. PCB layout practices that are
adequate for typical LDOs may degrade the PSRR, noise, or transient performance of the LM2936. Best
performance is achieved by placing CIN and COUT on the same side of the PCB as the LM2936, and as close as
is practical to the package. The ground connections for CIN and COUT should be back to the LM2936 ground pin
using as wide, and as short, of a copper trace as is practical.
Connections using long trace lengths, narrow trace widths, and/or connections through vias should be avoided
as these will add parasitic inductances and resistances that will give inferior performance, especially during
transient conditions

10.3 Thermal Considerations
Due to the power dissipation characteristics of the available packages (RθJA), full output current cannot be
ensured for all combinations of ambient temperature and input voltage.
Exceeding the maximum allowable power dissipation as defined by the final package RθJA will cause excessive
die junction temperature, and the regulator may go into thermal shutdown.
Power dissipation, PD, is calculated from the following formula:
PD = ((VIN – VOUT) × IOUT) + (VIN × IGND)

Figure 26. Current Paths for Power Dissipation Calculation
Knowing the power dissipation (PD), the thermal resistance of the package (RθJA), and the ambient temperature
(TA), the junction temperature (TJ) can be estimated using the following formula:
TJ = (PD × RθJA) + TA
(2)
Knowing the thermal resistance of the package (RθJA), the ambient temperature (TA), and the maximum allowed
operating junction temperature (TJ) of 125°C, the maximum power dissipation can be estimated using the
following formula:
PD(MAX) = (125°C – TA) / RθJA
(3)
Alternately, solving for the required thermal resistance (RθJA):
RθJA = (125°C – TA) / PD(MAX)
(4)
The maximum allowed PD information from Equation 3 can be used to estimate the maximum allowed load
current (IOUT), or the maximum allowed VIN:
VIN(MAX) = (PD(MAX) / IOUT) + VOUT
IOUT(MAX) = (PD(MAX) / (VIN – VOUT))
(5)
(6)
As an example, an application requires : VIN = 14 V, VOUT = 5 V, IOUT = 25 mA, and TA = 85°C. Find the
maximum RθJA to keep the junction temperature under 125°C.

≤ 177°C/W

(10)
The EIA/JEDEC standard (JESD51-2) provides methodologies to estimate the junction temperature from external
measurements (ΨJB references the temperature at the PCB, and ΨJT references the temperature at the top
surface of the package) when operating under steady-state power dissipation conditions. These methodologies
have been determined to be relatively independent of the copper thermal spreading area that may be attached to
the package DAP when compared to the more typical RθJA. Refer to Texas Instruments Application Report
Semiconductor and IC Package Thermal Metrics (SPRA953), for specifics.
On the 8-pin SOIC (D) package, the four ground pins are thermally connected to the backside of the die. Adding
approximately 0.04 square inches of 2 oz. copper pad area to these four pins will improve the JEDEC RθJA rating
from 111.4°C/W to approximately 100°C/W. If this extra copper area is placed directly beneath the SOIC
package there should not be any impact on board density.
The LM2936 has an internally set thermal shutdown point of typically 160°C. Thermal shutdown is outside the
ensured operating temperature range and is intended as a safety feature only. Continuous operation near the
thermal shutdown temperature should be avoided as it may have a negative affect on the life of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

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.
