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.
Dropout Voltage Typically 50 mV at 50 mA

Thermal Protection

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
.

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.
