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).

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.

During normal operation (where the input voltage is higher than the output) this diode is reverse biased (See Figure 38). LP2981-N 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) SCHOTTKY DIODE LP2981-N VIN VOUT PNP GND Figure 39. Adding External Schottky Diode Protection Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LP2981-N 13 LP2981-N SNOS773K – MARCH 2000 – REVISED APRIL 2013 www.ti.com 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. 14 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LP2981-N LP2981-N www.ti.com SNOS773K – MARCH 2000 – REVISED APRIL 2013 REVISION HISTORY Changes from Revision J (April 2013) to Revision K • Page Changed layout of National Data Sheet to TI format .......................................................................................................... 14 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LP2981-N 15 PACKAGE OPTION ADDENDUM www.ti.com 1-Nov-2013 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan Lead/Ball Finish MSL Peak Temp (2) (6) (3) Op Temp (°C) Device Marking (4/5) LP2981AIM5-2.5 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L0CA LP2981AIM5-2.5/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0CA LP2981AIM5-3.0/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L05A LP2981AIM5-3.3 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L04A LP2981AIM5-3.3/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L04A LP2981AIM5-3.6 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L0JA LP2981AIM5-3.6/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0JA LP2981AIM5-5.0 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L03A LP2981AIM5-5.0/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L03A LP2981AIM5X-3.0/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L05A LP2981AIM5X-3.3 NRND SOT-23 DBV 5 3000 TBD Call TI Call TI -40 to 125 L04A LP2981AIM5X-3.3/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L04A LP2981AIM5X-3.6/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0JA LP2981AIM5X-5.0 NRND SOT-23 DBV 5 3000 TBD Call TI Call TI -40 to 125 L03A LP2981AIM5X-5.0/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L03A LP2981IM5-2.5 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L0CB LP2981IM5-2.5/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0CB LP2981IM5-3.0/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L05B LP2981IM5-3.3 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L04B LP2981IM5-3.3/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L04B Addendum-Page 1 Samples PACKAGE OPTION ADDENDUM www.ti.com Orderable Device 1-Nov-2013 Status (1) LP2981IM5-3.6/NOPB Package Type Package Pins Package Drawing Qty ACTIVE SOT-23 DBV 5 1000 Eco Plan Lead/Ball Finish MSL Peak Temp (2) (6) (3) Op Temp (°C) Device Marking Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0JB (4/5) LP2981IM5-5.0 NRND SOT-23 DBV 5 1000 TBD Call TI Call TI -40 to 125 L03B LP2981IM5-5.0/NOPB ACTIVE SOT-23 DBV 5 1000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L03B LP2981IM5X-3.0/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L05B LP2981IM5X-3.3 NRND SOT-23 DBV 5 3000 TBD Call TI Call TI -40 to 125 L04B LP2981IM5X-3.3/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L04B LP2981IM5X-3.6/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L0JB LP2981IM5X-5.0 NRND SOT-23 DBV 5 3000 TBD Call TI Call TI -40 to 125 L03B LP2981IM5X-5.0/NOPB ACTIVE SOT-23 DBV 5 3000 Green (RoHS & no Sb/Br) CU SN Level-1-260C-UNLIM -40 to 125 L03B (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

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.
