(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The ESD rating of pins 3 and 4 for the SOT-23 package is 1 kV.
(4) 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.
(5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980-N output must be diode-clamped
to ground.
(6) 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 REVERSE CURRENT PATH).

APPLICATION HINTS
OUTPUT CAPACITOR
Like any low-dropout regulator, the LP2980-N requires an output capacitor to maintain regulator loop stability.
This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series
resistance (ESR) range. It is not difficult to find capacitors which meet the criteria of the LP2980-N, as the
acceptable capacitance and ESR ranges are wider than for most other LDOs.
In general, the capacitor value must be at least 1 μF (over the actual ambient operating temperature), and the
ESR must be within the range indicated in Figure 34, Figure 35 and Figure 36. It should be noted that, although
a maximum ESR is shown in these Figures, it is very unlikely to find a capacitor with ESR that high.
Tantalum Capacitors
Surface-mountable solid tantalum capacitors offer a good combination of small physical size for the capacitance
value, and ESR in the range needed by the LP2980-N.
The results of testing the LP2980-N stability with surface-mount solid tantalum capacitors show good stability
with values of at least 1 μF. The value can be increased to 2.2 μF (or more) for even better performance,
including transient response and noise.
Small value tantalum capacitors that have been verified as suitable for use with the LP2980-N are shown in
Table 1. Capacitance values can be increased without limit.
Aluminum Electrolytic Capacitors
Although probably not a good choice for a production design, because of relatively large physical size, an
aluminum electrolytic capacitor can be used in the design prototype for an LP2980-N regulator. A value of at
least 1 μF should be used, and the ESR must meet the conditions of Figure 34, Figure 35 and Figure 36. If the
operating temperature drops below 0°C, the regulator may not remain stable, as the ESR of the aluminum
electrolytic capacitor will increase, and may exceed the limits indicated in the Figures.

Multilayer Ceramic Capacitors
Surface-mountable multilayer ceramic capacitors may be an attractive choice because of their relatively small
physical size and excellent RF characteristics. However, they sometimes have ESR values lower than the
minimum required by the LP2980-N, and relatively large capacitance change with temperature. The
manufacturer's datasheet for the capacitor should be consulted before selecting a value.
Test results of LP2980-N stability using multilayer ceramic capacitors show that a minimum value of 2.2 μF is
usually needed for the 5V regulator. For the lower output voltages, or for better performance, a higher value
should be used, such as 4.7 μF.

REVERSE CURRENT PATH
The internal PNP power transistor used as the pass element in the LP2980-N has an inherent diode connected
between the regulator output and input. During normal operation (where the input voltage is higher than the
output) this diode is reverse biased (See Figure 37).

Figure 37. LP2980 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 38), to limit the reverse voltage
across the LP2980-N to 0.3V (See ABSOLUTE MAXIMUM RATINGS).

ON/OFF INPUT OPERATION
The LP2980-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 ensure 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 LP2980-N input voltage or another logic supply. The high-level voltage may exceed the LP2980-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.
IMPORTANT: The regulator shutdown function will not operate correctly if a slow-moving signal is used to drive
the ON/OFF input.

Increasing Output Current
Figure 39. 5V/400mA Regulator
The LP2980-N can be used to control higher-current regulators, by adding an external PNP pass device. With
the PNP transistors shown in Figure 39, the output current can be as high as 400 mA, as long as the input
voltage is held within the Safe Operation Boundary Curves shown below in Figure 40.
To ensure regulation, the minimum input voltage of this regulator is 6V. This “headroom” is the sum of the VBE of
the external transistor and the dropout voltage of the LP2980-N.
Notes:
1. Drive this input with a logic signal (see APPLICATION HINTS). If the shutdown function is not to be used, tie
the ON/OFF pin directly to the VIN pin.
2. Recommended devices (other PNP transistors can be used if the current gain and voltage ratings are
similar).
3. Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit.
4. Increasing the output capacitance improves transient response and increases phase margin.
5. Maximum safe input voltage and load current are limited by power dissipation in the PNP pass transistor and
the maximum ambient temperature for the specific application. If a TO-92 transistor such as the MPS2907A
is used, the thermal resistance from junction-to-ambient is 180°C/W in still air.
Assuming a maximum allowable junction temperature of 150°C for the MPS2907A device, the following curves
show the maximum VIN and IL values that may be safely used for several ambient temperatures.

Figure 41. 5V to 3.3V @ 3A Converter
With limited input voltage range, the LP2980-N can control a 3.3V, 3A regulator with the use of a high current-
gain external PNP pass transistor as shown in Figure 41. If the regulator is to be loaded with the full 3A, heat
sinking will be required on the pass transistor to keep it within its rated temperature range. Refer to Figure 42 .
For best load regulation at the high load current, the LP2980-N output voltage connection should be made as
close to the load as possible.
Although this regulator can handle a much higher load current than can the LP2980-N alone, it can be shut down
in the same manner as the LP2980-N. When the ON/OFF control is brought low, the converter will be in
shutdown, and will draw less than 1 μA from the source.
Notes:
1. Drive this input with a logic signal (see APPLICATION HINTS). If the shutdown function is not to be used, tie
the ON/OFF pin directly to the VIN pin.
2. Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit.
3. Increasing the output capacitance improves transient response and increases phase margin.
4. A heatsink may be required for this transistor. The maximum allowable value for thermal resistance of the
heatsink is dependent on ambient temperature and load current (see curves in Figure 42). Once the value is
obtained from the graph, a heatsink must be selected which has a thermal resistance equal to or lower than
this value. If the value is above 60°C/W, no heatsink is required (the TO-220 package alone will safely
dissipate this).
For these curves, a maximum junction temperature of 150°C is assumed for the pass transistor. The case-to-
heatsink attachment thermal resistance is assumed to be 1.5°C/W. All calculations are for 5.5V input voltage
(which is worst-case for power dissipation).

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.
