Submit Documentation Feedback 9 TLV702xx SLVSAG6B – SEPTEMBER 2010 – REVISED FEBRUARY 2011 www.ti.com APPLICATION INFORMATION The TLV702xx belongs to a new family of next-generation value LDO regulators. These devices consume low quiescent current and deliver excellent line and load transient performance. These characteristics, combined with low noise and very good PSRR with little (VIN – VOUT) headroom, make this family of devices ideal for portable RF applications. This family of regulators offers current limit and thermal protection, and is specified from –40°C to +125°C. INPUT AND OUTPUT CAPACITOR REQUIREMENTS 1.0-μF X5R- and X7R-type ceramic capacitors are recommended because these capacitors have minimal variation in value and equivalent series resistance (ESR) over temperature. However, the TLV702xx is designed to be stable with an effective capacitance of 0.1 μF or larger at the output. Thus, the device is stable with capacitors of other dielectric types as well, as long as the effective capacitance under operating bias voltage and temperature is greater than 0.1 μF. This effective capacitance refers to the capacitance that the LDO sees under operating bias voltage and temperature conditions; that is, the capacitance after taking both bias voltage and temperature derating into consideration. In addition to allowing the use of lower-cost dielectrics, this capability of being stable with 0.1-μF effective capacitance also enables the use of smaller footprint capacitors that have higher derating in size- and space-constrained applications. NOTE: Using a 0.1-μF rated capacitor at the output of the LDO does not ensure stability because the effective capacitance under the specified operating conditions would be less than 0.1 μF. Maximum ESR should be less than 200 mΩ. Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1-μF to 1.0-μF, low ESR capacitor across the IN pin and GND pin of the regulator. This capacitor counteracts reactive input sources and improves transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if large, fast rise-time load transients are anticipated, or if the device is not located close to the power source. If source impedance is more than 2 Ω, a 0.1-μF input capacitor may be necessary to ensure stability. BOARD LAYOUT RECOMMENDATIONS TO IMPROVE PSRR AND NOISE PERFORMANCE Input and output capacitors should be placed as close to the device pins as possible. To improve ac performance such as PSRR, output noise, and transient response, it is recommended that the board be designed with separate ground planes for VIN and VOUT, with the ground plane connected only at the GND pin of the device. In addition, the ground connection for the output capacitor should be connected directly to the GND pin of the device. High ESR capacitors may degrade PSRR performance. INTERNAL CURRENT LIMIT The TLV702xx internal current limit helps to protect the regulator during fault conditions. During current limit, the output sources a fixed amount of current that is largely independent of the output voltage. In such a case, the output voltage is not regulated, and is VOUT = ILIMIT × RLOAD. The PMOS pass transistor dissipates (VIN – VOUT) × ILIMIT until thermal shutdown is triggered and the device turns off. As the device cools, it is turned on by the internal thermal shutdown circuit. If the fault condition continues, the device cycles between current limit and thermal shutdown. See the Thermal Information section for more details. The PMOS pass element in the TLV702xx has a built-in body diode that conducts current when the voltage at OUT exceeds the voltage at IN. This current is not limited, so if extended reverse voltage operation is anticipated, external limiting to 5% of the rated output current is recommended. SHUTDOWN The enable pin (EN) is active high. The device is enabled when voltage at EN pin goes above 0.9V. This relatively lower value of voltage required to turn the LDO on can be exploited to power the LDO with a GPIO of recent processors whose GPIO Logic 1 voltage level is lower than traditional microcontrollers. The device is turned off when the EN pin is held at less than 0.4V. When shutdown capability is not required, EN can be connected to the IN pin. The TLV702xxP version has internal active pull-down circuitry that discharges the output with a time constant of: (120 · RL) t= · COUT (120 + RL) where: • • 10 Submit Documentation Feedback RL = Load resistance COUT = Output capacitor (1) © 2010–2011, Texas Instruments Incorporated TLV702xx SLVSAG6B – SEPTEMBER 2010 – REVISED FEBRUARY 2011 www.ti.com DROPOUT VOLTAGE The TLV702xx uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the PMOS device behaves as a resistor in dropout. As with any linear regulator, PSRR and transient response are degraded as (VIN – VOUT) approaches dropout. This effect is shown in Figure 15 in the Typical Characteristics section. TRANSIENT RESPONSE As with any regulator, increasing the size of the output capacitor reduces over-/undershoot magnitude but increases the duration of the transient response. UNDERVOLTAGE LOCKOUT (UVLO) The TLV702xx uses an undervoltage lockout circuit to keep the output shut off until internal circuitry is operating properly. THERMAL INFORMATION Thermal protection disables the output when the junction temperature rises to approximately +165°C, allowing the device to cool. When the junction temperature cools to approximately +145°C, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage as a result of overheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink. For reliable operation, junction temperature should be limited to +125°C maximum. To estimate the margin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal protection is triggered; use worst-case loads and signal conditions. The internal protection circuitry of the TLV702xx has been designed to protect against overload conditions. It was not intended to replace proper heatsinking. Continuously running the TLV702xx into thermal shutdown degrades device reliability. POWER DISSIPATION The ability to remove heat from the die is different for each package type, presenting different considerations in the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. Thermal performance data for TLV702xx were gathered using the TLV700 evaluation module (EVM), a 2-layer board with two ounces of copper per side. The dimensions and layout for the SOT23-5 (DBV) EVM are shown in Figure 25 and Figure 26. Corresponding thermal performance data are given in Table 1. Note that this board has provision for soldering not only the SOT23-5 package on the bottom layer, but also the SC-70 package on the top layer. The dimensions and layout of the SON-6 (DSE) EVM is shown in Figure 27 and Figure 28. Corresponding thermal performance data is again given in Table 1. Using heavier copper increases the effectiveness in removing heat from the device. The addition of plated through-holes to heat-dissipating layers also improves heatsink effectiveness. Power dissipation depends on input voltage and load conditions. Power dissipation (PD) is equal to the product of the output current and the voltage drop across the output pass element, as shown in Equation 2. PD = (VIN - VOUT) ´ IOUT (2) PACKAGE MOUNTING Solder pad footprint recommendations for the TLV702xx are available from the Texas Instruments web site at www.ti.com.

(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. 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.
