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).

LP2981  
www.ti.com ......................................................................................................................................................... SLVS521FJULY 2004REVISED AUGUST 2008  
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 mto 20 mand, thus, easily can  
fall out of minimum ESR requirements under certain operating conditions.  
If a ceramic capacitor is used at the output, a 1-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.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) 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.  
Addendum-Page 3  
PACKAGE OPTION ADDENDUM

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.
