DESCRIPTION/ORDERING INFORMATION  
The TPS72118 family of LDO regulators is available in fixed voltage options that are commonly used to power  
the latest DSPs and microcontrollers with a fixed output to 1.8 V. These regulators can be used in a wide variety  
of applications ranging from portable, battery-powered equipment to PC peripherals. The family features  
operation over a wide range of input voltages (1.8 V to 5.5 V) and low dropout voltage (150 mV at full load).  
Therefore, compared to many other regulators that require 2.5 V or higher input 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 3 µA in shutdown mode. These regulators can be  
operated very efficiently and, in a battery-powered application, help extend the longevity of the device.  
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.

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 is more efficient than if a regulator with a  
higher input voltage is used.  
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more  
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

SGDS037AOCTOBER 2007REVISED DECEMBER 2007  
APPLICATION INFORMATION  
The TPS72118 family of low-dropout (LDO) regulators functions with a very low input voltage (>1.8 V). The  
dropout voltage is typically 150 mV at full load. Typical quiescent current (ground pin current) is only 85 µA and  
drops to 3 µA in the shutdown mode.  
DEVICE OPERATION  
The TPS72118 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 3 µA. EN  
may be tied to VIN in applications where the shutdown feature is not used.  
Current limiting 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 increasing the output current. The thermal protection shuts the regulator off if the junction  
temperature rises above 170°C. Recovery is automatic when the junction temperature drops approximately 20°C  
below the high temperature trip point. 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 17.

DUAL SUPPLY APPLICATION  
In portable, battery-powered electronics, separate power rails for the DSP or microcontroller core voltage,  
V(CORE), and I/O peripherals (VIO) are usually necessary. The TPS72118 family of LDO linear regulators is ideal  
for providing V(CORE) for the DSP or microcontroller. As shown in Figure 18, two AAA batteries provide an input  
voltage to a boost converter. The batteries combine input voltage ranges from 3.0 V down to 1.8 V near the end  
of their useful lives. Therefore, a boost converter is necessary to provide the typical 3.3 V needed for VIO.  
Although there is no explicit circuitry to perform power-up sequencing of first V(CORE) then VIO, the output of the  
linear regulator reaches its regulated voltage much faster (< 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 VI of 1.8 V is appropriately chosen, this power supply solution 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.

EXTERNAL CAPACITOR REQUIREMENTS  
A 0.1-µF ceramic bypass capacitor is required on both the input and output for stability. Larger capacitors  
improve transient response, noise rejection, and ripple rejection. A higher value electrolytic input capacitor may  
be necessary if large, fast rise time load transient are anticipated, and/or there is significant input resistance from  
the device to the input power supply.  
POWER DISSIPATION AND JUNCTION TEMPERATURE  
Specified regulator operation is ensured 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, PD(max), and the actual dissipation, PD, which must be less than or equal to  
PD(max)  
.
The maximum power dissipation limit is determined using Equation 1 :  
T max * T

Where:  
TJmax is the maximum allowable junction temperature.  
θJA is the thermal resistance junction-to-ambient for the package; see the package dissipation rating table.  
TA is the ambient temperature.

The regulator dissipation is calculated using Equation 2:

  I  
D

(2)  
Power dissipation resulting from quiescent current is negligible.  
REGULATOR PROTECTION  
The TPS72118 pass element has a built-in back diode that safely conducts reverse current when the input  
voltage drops below the output voltage (for example, 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.  
The TPS72118 also features internal current limiting and thermal protection. During normal operation, the  
TPS72118 limits 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.

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)
