DESCRIPTION/ORDERING INFORMATION
The LP2981 family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both
portable and nonportable applications. Available in fixed voltages of 2.8 V, 3 V, 3.3 V, and 5 V, the family has an
output tolerance of 0.75% for the A-grade devices (1.25% for the standard grade) and is capable of delivering
100-mA continuous load current. Standard regulator features, such as overcurrent and overtemperature
protection, are included.
The LP2981 has features that make the regulator an ideal candidate for a variety of portable applications:
•
•
•
•
Low dropout: A PNP pass element allows a typical dropout of 200 mV at 100-mA load current and 7 mV at
1-mA load.
Low quiescent current: The use of a vertical PNP process allows for quiescent currents that are considerably
lower than those associated with traditional lateral PNP regulators.
Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01 µA when the
ON/OFF pin is pulled low.
Small packaging: For the most space-constrained needs, the regulator is available in the SOT-23 package.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The PNP pass transistor has a parasitic diode connected between the input and output. This diode normally is reverse biased
(VIN > VOUT), but will be forward biased if the output voltage exceeds the input voltage by a diode drop (see Application Information for
more details).
(3) If load is returned to a negative power supply, the output must be diode clamped to GND.
(4) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(5) The package thermal impedance is calculated in accordance with JESD 51-7.

(1) Dropout voltage is defined as the input-to-output differential at which the output voltage drops 100 mV below the value measured with a
1-V differential. This dropout specification does not apply to the 1.8-V option, as the minimum VIN = 2.2 V must be observed for proper
biasing of LDO control circuitry.
(2) The ON/OFF input must be actively terminated. Connect to VIN if this function is not used (see Application Information).

APPLICATION INFORMATION
Capacitors
Input Capacitor (Cin)
A minimum value of 1 µF (over the entire operating temperature range) is required at the input of the LP2981. In
addition, this input capacitor should be located within 1 cm of the input pin and connected to a clean analog
ground. There is no Equivalent Series Resistance (ESR) requirement for this capacitor, and the capacitance can
be increased without limit. A good quality ceramic or tantalum capacitor can be used.
Output Capacitor (Cout
)
As a PNP regulator, the LP2981 requires the output capacitor to meet both a minimum capacitance and ESR
value. Required ESR values as a function of load current are provided for various output voltages, load currents,
and capacitances (see Figure 2 through Figure 5).
•
•
Minimum Cout: 3.3 µF (can be increased without limit to improve transient response stability margin)
ESR range: see Figure 2 through Figure 5
It is critical that both the minimum capacitance and ESR requirement be met over the entire operating
temperature range. Depending on the type of capacitor used, both of these parameters can vary significantly with
temperature (see capacitor characteristics section).

Capacitor Characteristics
Ceramics
Due to their very low ESR values, ceramic capacitors are not suitable for use as the output capacitor. For
instance, a typical 2.2-µF ceramic capacitor has an ESR in the range of 10 mΩ to 20 mΩ and, thus, easily can
fall out of minimum ESR requirements under certain operating conditions.
If a ceramic capacitor is used at the output, a 1-Ω resistor should be placed in series with the capacitor to raise
the ESR seen by the regulator.
Tantalum
Solid tantalum capacitors are optimal choices for the LP2981, but they still must meet the minimum ESR
requirement. Note that the ESR of a tantalum capacitor increases as temperature drops, as much as doubling
from 25°C to –40°C. Thus, ESR margins must be maintained over the temperature range to prevent regulator
instability. For operation at very low temperatures, paralleling a tantalum capacitor with a ceramic one keeps the
combined ESR from increasing near the upper limit of the ESR curve.
Aluminum
Aluminum capacitors can be used, but use with the LP2981 is impractical due to their large physical dimensions.
They also must meet the ESR requirements over the full temperature range. In this regard, aluminium capacitors
are at a big disadvantage due to their sharp ESR increase as temperature drops. For example, over a
temperature drop from 20°C to –40°C, the ESR of an aluminum electrolytic capacitor can increase by a factor of
50. In addition, some of the electrolytes used in these capacitors can freeze at –25°C, making the capacitor
nonoperational.
ON/OFF Operation
The LP2981 allows for a shutdown mode via the ON/OFF pin. If the shutdown feature is not used, ON/OFF
should be connected to the input to ensure that the regulator is on at all times. To drive ON/OFF:
•
•
A LOW (≤0.3 V) turns the regulator OFF; a HIGH (≥1.6 V) turns it ON.
Use either a totem-pole output or an open-collector output with a pullup resistor tied to VIN (or another logic
supply). The HIGH signal can exceed VIN, but must not exceed the absolute maximum ratings of 20 V for the
ON/OFF pin.
•
Apply a signal with a slew rate of ≥40 mV/µs. A slow slew rate can cause the shutdown function to operate
incorrectly.

Reverse Input-Output Voltage
An inherent diode is present across the PNP pass element of the LP2981.
V
IN
V
OUT
With the anode connected to the output, this diode is reverse biased during normal operation, since the input
voltage is higher than the output. However, if the output is pulled one VBE higher than the input, or if the input is
abruptly stepped below the output, this diode is forward biased and can cause a parasitic silicon-controlled
rectifier (SCR) to latch, resulting in current flowing from the output to the input (values in excess of 100 mA can
cause damage). Thus, to prevent possible damage to the regulator in any application where the output may be
pulled above the input, an external Schottky diode must be connected between the output and input. With the
anode on output, this Schottky limits the reverse voltage across the output and input pins to 0.3 V, preventing
the regulator's internal diode from forward biasing.

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 Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information
provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and
continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.

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.
