DESCRIPTION
The REG710 is a switched capacitor voltage converter,
that produces a regulated, low-ripple output voltage from
an unregulated input voltage. A wide-input supply voltage
of 1.8V to 5.5V makes the REG710 ideal for a variety of
battery sources, such as single cell Li-Ion, or two and three
cell nickel- or alkaline-based chemistries.

Six Output Voltages Available:
5.5V, 5.0V, 3.3V, 3.0V, 2.7V, 2.5V
Small Packages:
− SOT23-6
− TSOT23-6 (REG71055 and REG71050 Only)
Evaluation Modules Available:
REG710EVM-33, REG710EVM-5
The input voltage may vary above and below the output
voltage and the output will remain in regulation. It works
equally well for step-up or step-down applications without
the need for an inductor, providing low EMI DC/DC
conversion. The high switching frequency allows the use
of small surface-mount capacitors, saving board space
and reducing cost. The REG710 is thermally protected and
current limited, protecting the load and the regulator during
fault conditions. Typical ground pin current (quiescent
current) is 65µA with no load, and less than 1µA in
shutdown mode. The 5.5V version of the REG710 is
available in a thin TSOT23-6 package. All other versions
are available in a small SOT23-6 package.

NOTE: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device
reliability.
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.

THEORY OF OPERATION
The REG710 regulated charge pump provides a regulated
output voltage for input voltages ranging from less than the
output to greater than the output. This is accomplished by automatic mode switching within the device. When the input
voltage is greater than the required output, the unit functions
as a variable frequency switch-mode regulator. This operation is shown in Figure 1. Transistors Q1 and Q3 are held off,
Q4 is on, and Q2 is switched as needed to maintain a regulated output voltage.
VIN
Q1
Q2
OFF
SWITCHED
CPUMP
Q3
During the second half cycle the FET switched are configured as shown in Figure 2B, and the voltage on CPUMP is
added to VIN. The output voltage is regulated by skipping
clock cycles as necessary.
PEAK CURRENT REDUCTION
In normal operation, the charging of the pump and output
capacitors usually leads to relatively high peak input currents which can be much higher than that of the average
load current. The regulator incorporates circuitry to limit
the input peak current, lowering the total EMI production of
the device and lowering output voltage ripple and input current ripple. Input capacitor (CIN) supplies most of the
charge required by input current peaks.

Operating in the Step-Down Mode
When the input voltage is less than the required output
voltage, the device switches to a step-up or boost mode of
operation, as shown in Figure 2.
A conversion clock of 50% duty cycle is generated. During
the first half cycle the FET switches are configured as
shown in Figure 2A, and CPUMP charges to VIN.
V IN
The regulator has thermal shutdown circuitry that protects
it from damage caused by overload conditions. The thermal protection circuitry disables the output when the junction temperature reached approximately 160°C, allowing
the device to cool. When the junction temperature cools to
approximately 140°C, the output circuitry is automatically
reenabled. Continuously running the regulator into thermal
shutdown can degrade reliability. The regulator also provides current limit to protect itself and the load.
SHUTDOWN MODE
A control pin on the regulator can be used to place the device into an energy-saving shutdown mode. In this mode,
the output is disconnected from the input as long as VIN is
greater than or equal to minimum VIN and the input quiescent current is reduced to 1µA maximum.

The approximate efficiency is given by:
Efficiency (%) = VOUT/(2 × VIN) × 100
(step-up operating mode)
CAPACITOR SELECTION
For minimum output voltage ripple, the output capacitor
COUT should be a ceramic, surface-mount type. Tantalum
capacitors generally have a higher Effective Series Resistance (ESR) and may contribute to higher output voltage
ripple. Leaded capacitors also increase ripple due to the
higher inductance of the package itself. To achieve best
operation with low input voltage and high load current, the
input and pump capacitors (CIN and CPUMP, respectively)
should also be surface-mount ceramic types. In all cases,
X7R or X5R dielectric are recommended. See the typical
operating circuit shown in Figure 3 for component values.

LAYOUT
Large transient currents flow in the VIN, VOUT, and GND
traces. To minimize both input and output ripple, keep the
capacitors as close as possible to the regulator using
short, direct circuit traces.
Figure 3. Typical Operating Circuit
With light loads or higher input voltage, a smaller 0.1µF
pump capacitor (CPUMP) and smaller 1µF input and output
capacitors (CIN and COUT, respectively) can be used. To
minimize output voltage ripple, increase the output capacitor, COUT, to 10µF or larger.
A suggested PCB routing is shown in Figure 4. The trace
lengths from the input and output capacitors have been
kept as short as possible.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
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

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

Reproduction of 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.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
