Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: Rating is for the human body mode, a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 3: The maximum allowable power dissipation is calculated by using PDMAX = (TJMAX - TA/θJA, where TJMAX is the maximum junction temperature, TA is the
ambient temperature, and θJA is the junction-to-ambient thermal resistance of the specified package. Therefore, the maximum power dissipation must be derated
at elevated temperatures and is limited by TJMAX, θJA and A.
Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2967 output must be diode-clamped to ground.
Note 5: The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity from VIN and VOUT
will turn on this diode.
Note 6: Load regulation excursion over temperature is included in Output Voltage Tolerance.
Note 7: The dropout voltage of a regulator is defined as the minimum input-to-output differential required to stay within 100mV of the output voltage measured with
a 1V differential.

LP2967-3.3V Region of Stability with 4.7 µF COUT
EXTERNAL CAPACITORS
The LP2967 low dropout regulator requires two external
capacitors, CIN and COUT to assure the device’s output
stability. CBYPASS may be used to reduce output noise. The
capacitors must be correctly selected with respect to capacitance values for all three capacitors and ESR value for
COUT.
Input Capacitor
An input capacitor with a minimum capacitance value of 1µF
is required between the LP2967 input and ground (the
amount of capacitance may be increased without limit). This
capacitor must be located a distance of not more than 0.5
inches from the input pin and returned to a clean analog
ground. Any good quality ceramic or tantalum may be used
for this capacitor.
10114207
LP2967-2.5V Region Of Stability with 10 µF COUT
Output Capacitor
The output capacitor must meet the requirement for minimum capacitance value of 2.2 µF and also have an appropriate ESR (equivalent series resistance) value. The LP2967
is actually designed to work with ceramic or tantalum output
capacitors, utilizing circuitry which allows the regulator to be
stable with an output capacitor whose ESR is as low as 4
mΩ. It may also be possible to use a film capacitor at the
output, but this type is not as attractive for reasons of size
and cost.
Important: The output capacitor must maintain its ESR in
the stable region over the full operating temperature range of
the application to assure stability. The minimum required
amount of output capacitance is 2.2 µF. Output capacitor
size can be increased without limit. It is important to remember that capacitor tolerance and variation with temperature
must be taken into consideration when selecting an output
capacitor so that the minimum required amount of output
capacitance is provided over the full operating temperature
range.

Application Hints
LP2967
Application Hints
ceramic capacitors is that their capacitance can vary with
temperature. Most large value ceramic capacitors are manufactured with the Z5U or Y5V temperature characteristic,
which results in the capacitance dropping by more than 50%
as the temperature goes from 25˚C to 85˚C. This could
cause problems if a 2.2 µF capacitor were used on the
output since it will drop down to approximately 1 µF at high
ambient temperatures. This could cause the LP2967 to oscillate. If Z5U or Y5V capacitors are used on the output, a
minimum capacitance value of 4.7 µF must be used.
(Continued)
LP2967-2.5V Region Of Stability with 2.2 µF COUT
A better choice for temperature coefficient in ceramic capacitors is X7R or X5R which hold the capacitance to within
± 15% over the full temperature range. Unfortunately, the
larger values of capacitance are not offered by all manufacturers in the X7R dielectric.
Tantalum
For the LP2967, tantalum capacitors are less desirable than
ceramic for use as output capacitors because they are typically more expensive when comparing equivalent capacitance and voltage ratings in the 2.2 µF to 4.7 µF range of
capacitance. Tantalum capacitors have good temperature
stability: a 4.7µF was tested and showed a 10% decline in
capacitance as the temperature was decreased from +125˚C
to −40˚C while the ESR increased by about 2:1 over the
same range of temperatures. This increase in ESR at lower
temperatures can cause oscillations when marginal quality
capacitors are used and the upper limit for ESR value is
exceeded.
10114265
No-Load Operation
If a 2.2 µF output capacitor is used, the minimum stable ESR
value rises to about 0.5 Ω at load currents below 1 mA. If
the minimum output load is < 1 mA (with COUT = 2.2 µF), a
Tantalum output capacitor should be used (the ESR of a
ceramic will be too low). It should be noted that if a 4.7 µF (or
larger) output capacitor is used, the part is fully stable with
either Tantalum or ceramic from no load to full load output
current.
Aluminum
The large physical size of aluminum electrolytic capacitors
make them unattractive for use with the LP2967. Their ESR
characteristics are also not well suited to the requirements of
LDO regulators. The ESR of an aluminum electrolytic is
higher than that of a tantalum, and it also varies greatly with
temperature. A typical aluminum electrolytic can exhibit an
ESR increase of 50X when going from 20˚C to −40˚C. Also,
some aluminum electrolytic capacitors can not be used below −25˚C because the electrolyte will freeze.
Bypass Capacitor
Connecting a 10 nF capacitor to the Bypass pin significantly
reduces noise on the regulator output. It should be noted that
the capacitor is connected directly to a high impedance
circuit in the bandgap reference. Because this circuit has
only a few microamperes flowing into it, any significant loading on this node will cause a change in the regulated output
voltage. For this reason, DC leakage current through the
noise bypass capacitor must never exceed 100 nA, and
should be kept as low as possible for best output voltage
accuracy. The types of capacitors best suited for the noise
bypass capacitor are ceramic and film capacitors. High quality ceramic capacitors with either NPO or COG dielectric
typically have very low leakage. 10 nF polypropylene and
polycarbonate film capacitors are available in small surface
mount packages and typically have extremely low leakage
current.
SHUTDOWN OPERATION
The two LDO regulators in the LP2967 have independent
shutdown pins. A low logic level signal at either of the shutdown pins SD1 or SD2 will turn off the corresponding regulator output VOUT1 or VOUT2. Pins SD1 and SD2 must be
terminated by tying them to VIN for a proper operation when
the shutdown function is not required.
CAPACITOR CHARACTERISTICS
REVERSE CURRENT PATH
The internal power transistor in the LP2967 has an inherent
parasitic diode. During normal operation, the input voltage is
higher than the output voltage and the parasitic diode is
reverse biased. However, if the output is pulled above the
input in an application, then current flows from the output to
the input if the parasitic diode gets forward biased. The
output can be pulled above the input as long as the current
in the parasitic diode is limited to 150mA.
Ceramic
Ceramic capacitors have the lowest ESR values, which
make them best for eliminating high frequency noise. The
outputs of LP2967 require a minimum of 2.2 µF of capacitance. The ESR of a typical 2.2 µF ceramic capacitor is in the
range of 4 mΩ to 20 mΩ, which easily meets the ESR limits
required for stability by the LP2967. One disadvantage of

ambient temperature coefficient (θJA) for an MSOP-8 package is 235˚C/W and the 8-bump micro SMD with minimum
copper area is 220˚C/W. The total power dissipation of the
device is given by:
PD = (VIN − VOUT1) IOUT1 + (VIN − VOUT2) IOUT2
(Continued)
MAXIMUM POWER DISSAIPATION CAPABILITY
Each output pin the LP2967 can deliver a current of up to
150mA over the full operating junction temperature range.
However, the maximum output current must be derated at
higher ambient temperature to ensure the junction temperature does not exceed 125˚C. Under all possible conditions,
the junction temperatures must be within the range specified
under operating conditions. The LP2967 is available in
MSOP-8 package and 8-bump micro SMD. The junction to
The maximum power dissipation, PDmax, that the device
can tolerate can be calculated by using the formula:
PDmax = (TJMAX − TA) / θJA
where TJMAX is the maximum specified junction temperature
(125˚C), and TA is the maximum ambient temperature.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
