FEATURES
voltages for operation, these regulators can be
operated directly from two AAA batteries. Also, the
typical quiescent current (ground pin current) is low,
starting at 85 µA during normal operation and 1 µA in
shutdown mode. Thus, these regulators can be
operated very efficiently and, in a battery-powered
application, help extend the longevity of the device.

Low Input Voltage Requirement
(Down to 1.8 V)
Small Output Capacitor, 0.1-µF
Similar LDO regulators require 1-µF or larger output
capacitors for stability. However, this regulator uses an
internal compensation scheme that stabilizes the
feedback loop over the full range of input voltages and
load currents with output capacitances as low as
0.1-µF. Ceramic capacitors of this size are relatively
inexpensive and available in small footprints.

5-Pin SOT-23 (DBV) Package
This family of regulators is particularly suited as a
portable power supply solution due to its minimal board
space requirement and 1.8-V minimum input voltage.
Being able to use two off-the-shelf, AAA, batteries
makes system design easier and also reduces
component cost. Moreover, the solution will be more
efficient than if a regulator with a higher input voltage is
used.

APPLICATION INFORMATION
TheTPS722xxfamilyoflow-dropout(LDO)regulatorsfunctionswithaverylowinputvoltage(>1.8V). Thedropoutvoltage
is typically 50 mV at full load. Typicalquiescentcurrent(groundpincurrent)isonly85 µA and drops to 1 µA in the shutdown
mode.
DEVICE OPERATION
TheTPS722xx family can be operated at low input voltages due to low voltage circuit design techniques and a PMOS pass
element that exhibits low dropout.
A logic low on the enable input, EN, shuts off the output and reduces the supply current to less than 1 µA. EN may be tied
to V in applications where the shutdown feature is not used.
IN
Currentlimiting and thermal protection prevent damage by excessive output current and/or power dissipation. The device
switches into a constant-current mode at approximately 350 mA; further load reduces the output voltage instead of
increasingthe output current. The thermal protection shuts the regulator off if the junction temperature rises above 170°C.
Recoveryisautomaticwhenthejunctiontemperaturedropsapproximately20°Cbelowthehightemperaturetrippoint. The
PMOS pass element includes a back diode that safely conducts reverse current when the input voltage level drops below
the output voltage level.
A typical application circuit is shown in Figure 16.

DUAL SUPPLY APPLICATION
In portable, battery-powered electronics, separate power rails for the DSP or microcontroller core voltage (V
) and I/O
CORE
peripherals (V ) are usually necessary. The TPS721xx family of LDO linear regulators is ideal for providing V
for
IO
(CORE)
the DSP or microcontroller. As shown in Figure 17, two AAA batteries provide an input voltage to a boost converter and
the TPS72115 LDO linear regulator. The batteries combine input voltage ranges from 3.0 V down to 1.8 V near the end
oftheirusefullives.Therefore,aboostconverterisnecessarytoprovidethetypical3.3VneededforV ,andtheTPS72115
IO
linear regulator provides a regulated V
voltage, which in this example is 1.5 V. Although there is no explicit circuitry
(CORE)
to perform power-up sequencing of first V
then V , the output of the linear regulator reaches its regulated voltage
(CORE)
IO
muchfaster (<400 µs) than the output of any switching type boost converter due to the inherent slow start up of those types
of converters. Assuming a boost converter with minimum V of 1.8 V is appropriately chosen, this power supply solution
I
can be used over the entire life of the two off-the-shelf AAA batteries. Thus, this solution is very efficient and the design
time and overall cost of the solution is minimized.

POWER DISSIPATION AND JUNCTION TEMPERATURE
Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature allowable
without damaging the device is 150°C. This restriction limits the power dissipation the regulator can handle in any given
application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation,
P
, and the actual dissipation, P , which must be less than or equal to P
.

Figure 18. TPS72201 Adjustable LDO Regulator Programming
REGULATOR PROTECTION
The TPS722xx pass element has a built-in back diode that safely conducts reverse current when the input voltage drops
below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally
limited. If extended reverse voltage is anticipated, external limiting might be appropriate.
TheTPS722xx also features internal current limiting and thermalprotection. Duringnormaloperation, theTPS722xxlimits
output current to approximately 350 mA. When current limiting engages, the output voltage scales back linearly until the
overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to
exceed the power dissipation ratings of the package. If the temperature of the device exceeds 170°C,thermal-protection
circuitry shuts it down. Once the device has cooled down to below 150°C, regulator operation resumes.

services.
Reproduction of significant portions of TI information in TI 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 reproduced
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.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources 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.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
