High PSRR is provided by a high gain, high bandwidth error loop with good supply rejection at very low headroom (VIN – VOUT). Fixed voltage versions provide a noise reduction pin to bypass noise generated by the bandgap reference and to improve PSRR while a quick-start circuit fast-charges this capacitor at startup. The combination of high performance and low ground current also make the TPS799xx an excellent choice for portable applications. All versions have thermal and over-current protection and are fully specified from –40°C to +125°C. Figure 28 shows the basic circuit connections for fixed voltage models. Figure 29 gives the connections for the adjustable output version (TPS79901). R1 and R2 can be calculated for any output voltage using the formula in Figure 29. Sample resistor values for common output voltages are shown in Figure 29. Input and Output Capacitor Requirements Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1µF to 1µF low ESR capacitor across the input supply near the regulator. This will counteract reactive input sources and improve transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if large, fast rise-time load transients are anticipated or the device is located several inches from the power source. If source impedance is not sufficiently low, a 0.1µF input capacitor may be necessary to ensure stability. The TPS799xx is designed to be stable with standard ceramic capacitors of values 2.2µF or larger. X5R and X7R type capacitors are best as they have minimal variation in value and ESR over temperature. Maximum ESR should be < 1.0Ω. The feedback capacitor, CFB, shown in Figure 29 is required for stability. For a parallel combination of R1 and R2 equal to 250kΩ, any value from 3pF to 1nF can be used. Fixed voltage versions have an internal 30pF feedback capacitor which is quick-charged at start-up. The adjustable version does not have this quick-charge circuit, so values below 5pF should be used to ensure fast startup; values above 47pF can be used to implement an output voltage soft-start. Larger value capacitors also improve noise slightly. The TPS79901 is stable in unity-gain configuration (OUT tied to FB) without CFB. Output Noise In most LDOs, the bandgap is the dominant noise source. If a noise reduction capacitor (CNR) is used with the TPS799xx, the bandgap does not contribute significantly to noise. Instead, noise is dominated by the output resistor divider and the error amplifier input. To minimize noise in a given application, use a 0.01µF noise reduction capacitor; for the adjustable version, smaller value resistors in the output resistor divider reduce noise. A parallel combination that gives 2µA of divider current will have the same noise performance as a fixed voltage version. To further optimize noise, equivalent series resistance of the output capacitor can be set to approximately 0.2Ω. This configuration maximizes phase margin in the control loop, reducing total output noise by up to 10%. space space space space Optional input capacitor. May improve source impedance, noise, or PSRR. Optional input capacitor. May improve source impedance, noise, or PSRR.

Noise can be minimized according to the above recommendations. Board Layout Recommendations to Improve PSRR and Noise Performance 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 each ground plane connected only at the GND pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to the GND pin of the device. Internal Current Limit The TPS799xx internal current limit helps protect the regulator during fault conditions. During current limit, the output will source a fixed amount of current that is largely independent of output voltage. For reliable operation, the device should not be operated in current limit for extended periods of time. The PMOS pass element in the TPS799xx 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 may be appropriate. Shutdown The enable pin (EN) is active high and is compatible with standard and low voltage TTL-CMOS levels. When shutdown capability is not required, EN can be connected to IN. Dropout Voltage The TPS799xx 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 its linear region of operation and the input-to-output resistance is the RDS, ON of the PMOS pass element. Because the PMOS device behaves like a resistor in dropout, VDO will approximately scale with output current. As with any linear regulator, PSRR and transient response are degraded as (VIN – VOUT) approaches dropout. This effect is shown in Figure 18 through Figure 20 in the Typical Characteristics section. Copyright © 2005–2007, Texas Instruments Incorporated SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007 Startup Fixed voltage versions of the TPS799xx use a quick-start circuit to fast-charge the noise reduction capacitor, CNR, if present (see Functional Block Diagrams, Figure 1). This allows the combination of very low output noise and fast start-up times. The NR pin is high impedance so a low leakage CNR capacitor must be used; most ceramic capacitors are appropriate in this configuration. Note that for fastest startup, VIN should be applied first, then the enable pin (EN) driven high. If EN is tied to IN, startup will be somewhat slower. Refer to Figure 25 and Figure 26 in the Typical Characteristics section. The quick-start switch is closed for approximately 135µs. To ensure that CNR is fully charged during the quick-start time, a 0.01µF or smaller capacitor should be used. Transient Response As with any regulator, increasing the size of the output capacitor will reduce over/undershoot magnitude but increase duration of the transient response. In the adjustable version, adding CFB between OUT and FB will improve stability and transient response. The transient response of the TPS799xx is enhanced by an active pull-down that engages when the output overshoots by approximately 5% or more when the device is enabled. When enabled, the pull-down device behaves like a 350Ω resistor to ground. Under-Voltage Lock-Out (UVLO) The TPS799xx utilizes an under-voltage lock-out circuit to keep the output shut off until internal circuitry is operating properly. The UVLO circuit has a de-glitch feature so that it will typically ignore undershoot transients on the input if they are less than 50µs duration. Minimum Load The TPS799xx is stable and well-behaved with no output load. To meet the specified accuracy, a minimum load of 500µA is required. Below 500µA at junction temperatures near +125°C, the output can drift up enough to cause the output pull-down to turn on. The output pull-down will limit voltage drift to 5% typically but ground current could increase by approximately 50µA. In typical applications, the junction cannot reach high temperatures at light loads since there is no appreciable dissipated power. The specified ground current would then be valid at no load in most applications. Submit Documentation Feedback 11 TPS799xx www.ti.com SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007 Thermal Information Thermal Protection Power Dissipation 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 due to overheating. The ability to remove heat from the die is different for each package type, presenting different considerations in the PCB layout. The PCB area around the device that is free of other components moves the head from the device to the ambient air. Performance data for JEDEC low- and high-K boards are given in the Dissipation Ratings table. Using heavier copper will increase the effectiveness in removing heat from the device. The addition of plated through-holes to heat-dissipating layers will also improve the heatsink effectiveness. 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. For good reliability, thermal protection should trigger at least +35°C above the maximum expected ambient condition of your particular application. This configuration produces a worst-case junction temperature of +125°C at the highest expected ambient temperature and worst-case load. Power dissipation depends on input voltage and load conditions. Power dissipation is equal to the product of the output current time the voltage drop across the output pass element, as shown in Equation 2: P D + ǒVIN*V OUTǓ @ I OUT (2) Package Mounting Solder pad footprint recommendations for the TPS799xx are available from the Texas Instruments' web site at www.ti.com. The internal protection circuitry of the TPS799xx has been designed to protect against overload conditions. It was not intended to replace proper heatsinking. Continuously running the TPS799xx into thermal shutdown will degrade device reliability. 1,060 0,960 1,427 1,327 (d = 0.30 ±0.05) 0,625 Max NOTES: A. All linear dimensions are in millimeters. B.

Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. 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 the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI 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. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
