A wide Low Input Current Ripple input supply voltage of 1.8V to 5.5V makes the Low Output Voltage Ripple REG710 ideal for a variety of battery sources, such Minimum Number of External as single-cell Li-Ion, or two- and three-cell nickel- or alkaline-based chemistries. Components No Inductors 1MHz Internal Oscillator Allows Small The input voltage may vary above and below the Capacitors output voltage and the output remains in regulation. It works equally well for step-up or step-down Shutdown Mode inductor, Thermal and Current Limit Protection providing low EMI dc/dc conversion. The high Six Output Voltages Available: switching frequency allows the use of small surface-mount capacitors, saving board space and 5.5V, 5.0V, 3.3V, 3.0V, 2.7V, 2.5V reducing cost. The REG710 is thermally protected Small Packages: and current limited, protecting the load and the SOT23-6 regulator during fault conditions.

(1) REG710 SBAS221G DECEMBER 2001 REVISED JANUARY 2009 www.ti.com 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.

When the junction temperature cools to approximately +140 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. The EN pin enables the IC when pulled high and places it into energy-saving shutdown mode when pulled low. When in shutdown mode, the output is disconnected from the input and the quiescent current is reduced to 0.01 µ A typical.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) 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.

www.ti.com 17-Aug-2012 Addendum-Page 3 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 temperature.
