FEATURES  
DESCRIPTION  
The LM2990 is a three-terminal, low dropout, 1  
ampere negative voltage regulator available with fixed  
output voltages of −5, −5.2, −12, and −15V.

Output Current in Excess of 1A  
The LM2990 uses new circuit design techniques to  
provide low dropout and low quiescent current. The  
dropout voltage at 1A load current is typically 0.6V  
and an ensured worst-case maximum of 1V over the  
entire operating temperature range. The quiescent  
current is typically 1 mA with 1A load current and an  
input-output voltage differential greater than 3V. A  
unique circuit design of the internal bias supply limits  
the quiescent current to only 9 mA (typical) when the  
regulator is in the dropout mode (VOUT − VIN ≤ 3V).  
Output voltage accuracy is ensured to ±5% over load,  
and temperature extremes.

Post Switcher Regulator  
Local, On-Card, Regulation  
Battery Operated Equipment  
The LM2990 is short-circuit proof, and thermal  
shutdown includes hysteresis to enhance the  
reliability of the device when overloaded for an  
extended period of time. The LM2990 is available in a  
3-lead package and is rated for operation over the  
automotive temperature range of −40°C to +125°C.  
Typical Application  
*Required if the regulator is located further than 6 inches from the power supply filter capacitors. A 1 μF solid  
tantalum or a 10 μF aluminum electrolytic capacitor is recommended.  
**Required for stability. Must be at least a 10 μF aluminum electrolytic or a 1 μF solid tantalum to maintain stability.  
May be increased without bound to maintain regulation during transients. Locate the capacitor as close as possible to  
the regulator. The equivalent series resistance (ESR) is critical, and should be less than 10Ω over the same operating  
temperature range as the regulator.

(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and  
specifications.  
(3) Human body model, 100 pF discharged through a 1.5 kΩ resistor.  
(4) The maximum power dissipation is a function of TJmax, θJA, and TA. The maximum allowable power dissipation at any ambient  
temperature is PD = (TJmax − TA)/θJA. If this dissipation is exceeded, the die temperature will rise above 125°C, and the LM2990 will  
eventually go into thermal shutdown at a TJ of approximately 160°C. For the LM2990, the junction-to-ambient thermal resistance, is  
53°C/W, 73°C/W for the DDPAK/TO-263, and the junction-to-case thermal resistance is 3°C. If the DD[AK/TO-263 package is used, the  
thermal resistance can be reduced by increasing the P.C. board copper area thermally connected to the package. Using 0.5 square  
inches of copper area, θJA is 50°C/W; with 1 square inch of copper area, θJA is 37°C/W; and with 1.6 or more square inches of copper  
area, θJA is 32°C/W.

(3) Limits are specified and 100% production tested.  
(4) The short circuit current is less than the maximum output current with the −12V and −15V versions due to internal foldback current  
limiting. The −5V and −5.2V versions, tested with a lower input voltage, does not reach the foldback current limit and therefore conducts  
a higher short circuit current level. If the LM2990 output is pulled above ground, the maximum allowed current sunk back into the  
LM2990 is 1.5A.

Definition of Terms  
Dropout Voltage: The input-output voltage differential at which the circuit ceases to regulate against further  
reduction in input voltage. Measured when the output voltage has dropped 100 mV from the nominal value  
obtained at (VO + 5V) input, dropout voltage is dependent upon load current and junction temperature.  
Input Voltage: The DC voltage applied to the input terminals with respect to ground.  
Input-Output Differential: The voltage difference between the unregulated input voltage and the regulated  
output voltage for which the regulator will operate.  
Line Regulation: The change in output voltage for a change in the input voltage. The measurement is made  
under conditions of low dissipation or by using pulse techniques such that the average chip temperature is  
not significantly affected.  
Load Regulation: The change in output voltage for a change in load current at constant chip temperature.  
Long Term Stability: Output voltage stability under accellerated life-test conditions after 1000 hours with  
maximum rated voltage and junction temperature.  
Output Noise Voltage: The rms AC voltage at the output, with constant load and no input ripple, measured over  
a specified frequency range.  
Quiescent Current: That part of the positive input current that does not contribute to the positive load current.  
The regulator ground lead current.  
Ripple Rejection: The ratio of the peak-to-peak input ripple voltage to the peak-to-peak output ripple voltage.  
Temperature Stability of VO:The percentage change in output voltage for a thermal variation from room  
temperature to either temperature extreme.

(1) The maximum power dissipation is a function of TJmax, θJA, and TA. The maximum allowable power dissipation at any ambient  
temperature is PD = (TJmax − TA)/θJA. If this dissipation is exceeded, the die temperature will rise above 125°C, and the LM2990 will  
eventually go into thermal shutdown at a TJ of approximately 160°C. For the LM2990, the junction-to-ambient thermal resistance, is  
53°C/W, 73°C/W for the DDPAK/TO-263, and the junction-to-case thermal resistance is 3°C. If the DD[AK/TO-263 package is used, the  
thermal resistance can be reduced by increasing the P.C. board copper area thermally connected to the package. Using 0.5 square  
inches of copper area, θJA is 50°C/W; with 1 square inch of copper area, θJA is 37°C/W; and with 1.6 or more square inches of copper  
area, θJA is 32°C/W.

APPLICATION HINTS  
EXTERNAL CAPACITORS  
The LM2990 regulator requires an output capacitor to maintain stability. The capacitor must be at least 10 μF  
aluminum electrolytic or 1 μF solid tantalum. The output capacitor's ESR must be less than 10Ω, or the zero  
added to the regulator frequency response by the ESR could reduce the phase margin, creating oscillations  
(refer to the graph on the right). An input capacitor, of at least 1 μF solid tantalum or 10 μF aluminum electrolytic,  
is also needed if the regulator is situated more than 6″ from the input power supply filter.  
FORCING THE OUTPUT POSITIVE  
Due to an internal clamp circuit, the LM2990 can withstand positive voltages on its output. If the voltage source  
pulling the output positive is DC, the current must be limited to 1.5A. A current over 1.5A fed back into the  
LM2990 could damage the device. The LM2990 output can also withstand fast positive voltage transients up to  
26V, without any current limiting of the source. However, if the transients have a duration of over 1 ms, the  
output should be clamped with a Schottky diode to ground.

(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.  
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.
