Thus the power dissipation is dependent on the ambient temperature and the thermal resistance across the various interfaces between the die and ambient air. Re-stating the equation given in (1) in the electrical specification section, the allowable power dissipation for the device in a given package can be calculated: (1) With a θJA = 255°C/W, the device in the DSBGA package returns a value of 392 mW with a maximum junction temperature of 125°C. The actual power dissipation across the device can be represented by the following equation: PD = (VIN − VOUT) x IOUT. (2) This establishes the relationship between the power dissipation allowed due to thermal consideration, the voltage drop across the device, and the continuous current capability of the device. These two equations should be used to determine the optimum operating conditions for the device in the application. EXTERNAL CAPACITORS In common with most regulators, the LP3999 requires external capacitors to ensure stable operation. The LP3999 is specifically designed for portable applications requiring minimum board space and smallest components. These capacitors must be correctly selected for good performance. INPUT CAPACITOR An input capacitor is required for stability. It is recommended that a 1.0 µF capacitor be connected between the LP3999 input pin and ground (this capacitance value may be increased without limit). This capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean analogue ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input. Important: Tantalum capacitors can suffer catastrophic failures due to surge current when connected to a lowimpedance source of power (like a battery or a very large capacitor). If a tantalum capacitor is used at the input, it must be ensured by the manufacturer to have a surge current rating sufficient for the application. There are no requirements for the ESR (Equivalent Series Resistance) on the input capacitor, but tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the capacitance will remain ≅ 1.0 µF over the entire operating temperature range. OUTPUT CAPACITOR The LP3999 is designed specifically to work with very small ceramic output capacitors. A ceramic capacitor (dielectric types Z5U, Y5V or X7R) in the 1.0 [to 10 µF] range, and with ESR between 5 mΩ to 500 mΩ, is suitable in the LP3999 application circuit. For this device the output capacitor should be connected between the VOUT pin and ground. It may also be possible to use tantalum or film capacitors at the device output, VOUT, but these are not as attractive for reasons of size and cost (see the section CAPACITOR CHARACTERISTICS). The output capacitor must meet the requirement for the minimum value of capacitance and also have an ESR value that is within the range 5 mΩ to 500 mΩ for stability. (1) 10 In applications where high power dissipation and/or poor thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA(max)) is dependant on the maximum operating junction temperature (TJ(max-op)), the maximum power dissipation (PD(max)), and the junction to ambient thermal resistance in the application (θJA). This relationship is given by: TA(max) = TJ(max-op) − (PD(max) × θJA). Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LP3999 LP3999 www.ti.com SNVS207E – JUNE 2003 – REVISED MAY 2013 NO-LOAD STABILITY The LP3999 will remain stable and in regulation with no external load. This is an important consideration in some circuits, for example CMOS RAM keep-alive applications. CAPACITOR CHARACTERISTICS The LP3999 is designed to work with ceramic capacitors on the output to take advantage of the benefits they offer. For capacitance values in the range of 1 µF to 4.7 µF, ceramic capacitors are the smallest, least expensive and have the lowest ESR values, thus making them best for eliminating high frequency noise. The ESR of a typical 1 µF ceramic capacitor is in the range of 20 mΩ to 40 mΩ, which easily meets the ESR requirement for stability for the LP3999. The temperature performance of ceramic capacitors varies by type. Most large value ceramic capacitors (≥ 2.2 µF) are manufactured with Z5U or Y5V temperature characteristics, which results in the capacitance dropping by more than 50% as the temperature goes from 25°C to 85°C. A better choice for temperature coefficient in a ceramic capacitor is X7R. This type of capacitor is the most stable and holds the capacitance within ±15% over the temperature range. Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more expensive when comparing equivalent capacitance and voltage ratings in the 1 µF to 4.7 µF range. Another important consideration is that tantalum capacitors have higher ESR values than equivalent size ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic capacitor with the same ESR value. It should also be noted that the ESR of a typical tantalum will increase about 2:1 as the temperature goes from 25°C down to −40°C, so some guard band must be allowed. NOISE BYPASS CAPACITOR A bypass capacitor should be connected between the CBYPASS pin and ground to significantly reduce the noise at the regulator output. This device pin connects directly to a high impedance node within the bandgap reference circuitry. Any significant loading on this node will cause a change on the regulated output voltage. For this reason, DC leakage current through this pin must be kept as low as possible for best output voltage accuracy. The use of a 0.01µF bypass capacitor is strongly recommended to prevent overshoot on the output during startup. The types of capacitors best suited for the noise bypass capacitor are ceramic and film. High quality ceramic capacitors with NPO or COG dielectric typically have very low leakage. Polypropolene and polycarbonate film capacitors are available in small surface-mount packages and typically have extremely low leakage current. Unlike many other LDO’s, the addition of a noise reduction capacitor does not effect the transient response of the device. ENABLE OPERATION The LP3999 may be switched ON or OFF by a logic input at the ENABLE pin, VEN. A high voltage at this pin will turn the device on. When the enable pin is low, the regulator output is off and the device typically consumes 3 nA. If the application does not require the shutdown feature, the VEN pin should be tied to VIN to keep the regulator output permanently on. To ensure proper operation, the signal source used to drive the VEN input must be able to swing above and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section under VIL and VIH. FAST TURN ON Fast turn-on is ensured by control circuitry within the reference block allowing a very fast ramp of the output voltage to reach the target voltage. There is no active turn-off on this device. Refer to LP3995 for a similar device with active turn-off. DSBGA MOUNTING The DSBGA package requires specific mounting techniques which are detailed in TI's AN-1112 Application Report (SNVA009).

For best results during assembly, alignment ordinals on the PC board may be used to facilitate placement of the DSBGA device. DSBGA LIGHT SENSITIVITY Exposing the DSBGA device to direct sunlight will cause incorrect operation of the device. Light sources such as halogen lamps can affect electrical performance if they are situated in proximity to the device. Light with wavelengths in the red and infra-red part of the spectrum have the most detrimental effect thus the fluorescent lighting used inside most buildings has very little effect on performance. Tests carried out on a DSBGA test board showed a negligible effect on the regulated output voltage when brought within 1 cm of a fluorescent lamp. A deviation of less than 0.1% from nominal output voltage was observed. 12 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LP3999 LP3999 www.ti.com SNVS207E – JUNE 2003 – REVISED MAY 2013 REVISION HISTORY Changes from Revision D (May 2013) to Revision E • Page Changed layout of National Data Sheet to TI format .......................................................................................................... 12 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: LP3999 13 PACKAGE OPTION ADDENDUM www.ti.com 8-Oct-2015 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) LP3999ITL-1.8/NOPB ACTIVE DSBGA YZR 5 250 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITL-2.4/NOPB ACTIVE DSBGA YZR 5 250 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITL-2.5/NOPB ACTIVE DSBGA YZR 5 250 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITL-3.3/NOPB ACTIVE DSBGA YZR 5 250 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITLX-1.8/NOPB ACTIVE DSBGA YZR 5 3000 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITLX-2.5/NOPB ACTIVE DSBGA YZR 5 3000 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITLX-2.8/NOPB ACTIVE DSBGA YZR 5 3000 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 LP3999ITLX-3.3/NOPB ACTIVE DSBGA YZR 5 3000 Green (RoHS & no Sb/Br) SNAGCU Level-1-260C-UNLIM -40 to 125 9 (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.
