Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
The ESD rating of pins 3 and 4 for the SOT-23 package is 1 kV.
The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal
resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated
using:
The value of θJA for the SOT-23 package is 220°C/W. Exceeding the maximum allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2981-N output must be diode-clamped
to ground.
The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity
from VIN to VOUT will turn on this diode (see APPLICATION HINTS).

Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a
1V differential.
The ON/OFF inputs must be properly driven to prevent misoperation. For details, refer to APPLICATION HINTS.

APPLICATION HINTS
EXTERNAL CAPACITORS
Like any low-dropout regulator, the external capacitors used with the LP2981-N must be carefully selected to
assure regulator loop stability.
Input Capacitor:
An input capacitor whose value is ≥ 1 μF is required with the LP2981-N (amount of capacitance can be increased
without limit).
This capacitor must be located a distance of not more than 0.5″ from the input pin of the LP2981-N and returned
to a clean analog ground. Any good quality ceramic or tantalum can be used for this capacitor.
Output Capacitor:
The output capacitor must meet both the requirement for minimum amount of capacitance and E.S.R. (equivalent
series resistance) value. Curves are provided which show the allowable ESR range as a function of load current
for various output voltages and capacitor values (refer to Figure 34, Figure 35, Figure 36, and Figure 37).
NOTE
Important: The output capacitor must maintain its ESR in the stable region over the full
operating temperature range to assure stability. Also, capacitor tolerance and variation
with temperature must be considered to assure the minimum amount of capacitance is
provided at all times.
This capacitor should be located not more than 0.5″ from the output pin of the LP2981-N and returned to a clean
analog ground.
CAPACITOR CHARACTERISTICS
Tantalum:
Tantalum capacitors are the best choice for use with the LP2981-N. Most good quality tantalums can be used
with the LP2981-N, but check the manufacturer's data sheet to be sure the ESR is in range.
It is important to remember that ESR increases at lower temperatures and a capacitor that is near the upper limit
for stability at room temperature can cause instability when it gets cold.
In applications which must operate at very low temperatures, it may be necessary to parallel the output tantalum
capacitor with a ceramic capacitor to prevent the ESR from going up too high (see below for important
information on ceramic capacitors).
Ceramic:
Ceramic capacitors are not recommended for use at the output of the LP2981-N. This is because the ESR of a
ceramic can be low enough to go below the minimum stable value for the LP2981-N. A 2.2 μF ceramic was
measured and found to have an ESR of about 15 mΩ, which is low enough to cause oscillations.
If a ceramic capacitor is used on the output, a 1Ω resistor should be placed in series with the capacitor.
Aluminum:
Because of large physical size, aluminum electrolytics are not typically used with the LP2981-N. They must meet
the same ESR requirements over the operating temperature range, more difficult because of their steep increase
at cold temperature.
An aluminum electrolytic can exhibit an ESR increase of as much as 50X when going from 20°C to −40°C. Also,
some aluminum electrolytics are not operational below −25°C because the electrolyte can freeze.

REVERSE CURRENT PATH
The internal PNP power transistor used as the pass element in the LP2981-N has an inherent diode connected
between the regulator output and input. During normal operation (where the input voltage is higher than the
output) this diode is reverse biased (See Figure 38).

VIN
VOUT
PNP
GND
Figure 38. LP2981-N Reverse Current Path
However, if the input voltage is more than a VBE below the output voltage, this diode will turn ON and current will
flow into the regulator output. In such cases, a parasitic SCR can latch which will allow a high current to flow into
the VIN pin and out the ground pin, which can damage the part.
The internal diode can also be turned on if the input voltage is abruptly stepped down to a voltage which is a VBE
below the output voltage.
In any application where the output voltage may be higher than the input voltage, an external Schottky diode
must be connected from VIN to VOUT (cathode on VIN, anode on VOUT. See Figure 39), to limit the reverse voltage
across the LP2981-N to 0.3V (see Absolute Maximum Ratings)

ON/OFF INPUT OPERATION
The LP2981-N is shut off by pulling the ON/OFF input low, and turned on by driving the input high. If this feature
is not to be used, the ON/OFF input should be tied to VIN to keep the regulator on at all times (the ON/OFF input
must not be left floating).
To ensure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and
below the specified turn-on/turn-off voltage thresholds which specify an ON or OFF state (see ELECTRICAL
CHARACTERISTICS).
The ON/OFF signal may come from either a totem-pole output, or an open-collector output with pull-up resistor to
the LP2981-N input voltage or another logic supply. The high-level voltage may exceed the LP2981-N input
voltage, but must remain within the Absolute Maximum Ratings for the ON/OFF pin.
It is also important that the turn-on/turn-off voltage signals applied to the ON/OFF input have a slew rate which is
greater than 40 mV/μs.
NOTE
IMPORTANT: The regulator shutdown function will not operate correctly if a slow-moving
signal is applied to the ON/OFF input.

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)

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.
