High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 40-μA (typical) ground current. 1 • • • • • • • • 200-mA Low-Dropout Regulator With EN Multiple Output Voltage Versions Available: – Fixed Outputs of 1.2 V to 4.5 V Using Innovative Factory EEPROM Programming – Adjustable Outputs from 1.20 V to 6.5 V Inrush Current Protection with EN Toggle Low IQ: 40 μA High PSRR: 66 dB at 1 kHz Stable with a Low-ESR, 2-μF Typical Output Capacitance Excellent Load and Line Transient Response 2% Overall Accuracy (Load, Line, and Temperature) Very Low Dropout: 100 mV Package: 5-Bump, Thin, 1-mm × 1.37-mm DSBGA The TPS799 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100 mV at a 200-mA output. The TPS799 uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS799 features inrush current protection when the EN toggle is used to start the device, immediately clamping the current. All devices are fully specified over the temperature range of TJ = –40°C to 125°C, and offered in a lowprofile, die-sized ball grid array (DSBGA) package, ideal for wireless handsets and WLAN cards.

High PSRR is provided by a high-gain, highbandwidth error loop with good supply rejection at very low headroom (VIN – VOUT). A noise-reduction pin is provided to bypass noise generated by the band-gap reference and to improve PSRR, while a quick-start circuit quickly charges this capacitor at start-up. The combination of high performance and low ground current also make these devices an excellent choice for portable applications. All versions have thermal and overcurrent protection, and are fully specified from –40°C to 125°C. The TPS799 family also features inrush current protection with an EN toggle start-up, and overshoot detection at the output. When the EN toggle is used to start the device, current limit protection is immediately activated, restricting the inrush current to the device. If voltage at the output overshoots 5% from the nominal value, a pulldown resistor reduces the voltage to normal operating conditions, as shown in the Functional Block Diagram. 7.2 Functional Block Diagram IN OUT 400Ω 2µA Current Limit Overshoot Detect Thermal Shutdown EN UVLO Quickstart 1.193V Bandgap NR 500k GND Figure 26.

Adjustable-Voltage Versions 7.3 Feature Description 7.3.1 Internal Current Limit The TPS799 internal current limit helps protect the regulator during fault conditions. In current limit mode, the output sources a fixed amount of current that is largely independent of the output voltage. For reliable operation, do not operate the device in a current-limit state for extended periods of time. The PMOS pass element in the TPS799 has a built-in body diode that conducts current when the voltage at OUT exceeds the voltage at IN. This current is not limited; therefore, if extended reverse voltage operation is anticipated, external limiting may be required. 7.3.2 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. 7.3.3 Start Up The TPS799 uses a start-up circuit to quickly charge the noise reduction capacitor, CNR, if present (see the Functional Block Diagram). This circuit allows for 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 for this configuration. Note that for fastest start-up, apply VIN first, and then drive the enable pin (EN) high. If EN is tied to IN, start-up is somewhat slower. The start-up switch is closed for approximately 135 μs. To ensure that CNR is fully charged during start-up, use a 0.01-μF or smaller capacitor. 7.3.4 Undervoltage Lockout (UVLO) The TPS799 uses an undervoltage lockout circuit to keep the output shut off until internal circuitry is operating properly. The UVLO circuit has a deglitch feature so that undershoot transients are typically ignored on the input if these transients are less than 50 μs in duration. 7.4 Device Functional Modes Driving EN over 1.2 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode, thus reducing the operating current to 150 nA, nominal.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The TPS799 family of LDO regulators provides high PSRR while maintaining ultralow current consumption. The family also features inrush current protection and overshoot detection at the output. 8.2 Typical Applications Figure 28 and Figure 29 show the basic circuit connections.

Typical Application Circuit for Adjustable Voltage Version 8.2.1 Design Requirements Select the desired device based on the output voltage. Provide an input supply with adequate headroom to account for dropout and output current to account for the GND terminal current, and power the load. 8.2.2 Detailed Design Procedure 8.2.2.1 Input and Output Capacitor Requirements Although an input capacitor is not required for stability, good analog design practice is to connect a 0.1-μF to 1-μF low ESR capacitor across the input supply near 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 located several inches from the power source. If source impedance is not sufficiently low, a 0.1-μF input capacitor may be necessary to ensure stability. 14 Submit Documentation Feedback Copyright © 2005–2015, Texas Instruments Incorporated Product Folder Links: TPS799 TPS799 www.ti.com SBVS056K – JANUARY 2005 – REVISED JANUARY 2015 Typical Applications (continued) The TPS799 is designed to be stable with standard ceramic capacitors with values of 2.2 μF or greater. X5Rand X7R-type capacitors are best because they have minimal variation in value and ESR over temperature. Maximum ESR must be less than 1.0 Ω. 8.2.2.2 Output Noise In most LDOs, the band gap is the dominant noise source. If a noise-reduction capacitor (CNR) is used with the TPS799, the band gap 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 0.01-μF noise reduction capacitor. To further optimize noise, equivalent series resistance of the output capacitor can be set to approximately 0.2 Ω. This configuration maximizes phase margin in the control loop, reducing total output noise by up to 10%. Noise can be referred to the feedback point; with CNR = 0.01 μF total noise is approximately given by Equation 1: 10.5mVRMS VN = x VOUT V (1) 8.2.2.3 Dropout Voltage The TPS799 uses a PMOS pass transistor to achieve a low dropout voltage. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in its linear region of operation and rDS(on) of the PMOS pass element is the input-to-output resistance. Because the PMOS device behaves like a resistor in dropout, VDO approximately scales with the output current. As with any linear regulator, PSRR degrades as (VIN – VOUT) approaches dropout. This effect is illustrated in Figure 10 through Figure 18 in the Typical Characteristics section. 8.2.2.4 Transient Response As with any regulator, increasing the size of the output capacitor reduces over- and undershoot magnitude, but increases the duration of the transient response. The transient response of the TPS799 is enhanced by an active pulldown device that engages when the output overshoots by approximately 5% or more when the device is enabled. When enabled, the pulldown device behaves like a 350-Ω resistor to ground. 8.2.2.5 Minimum Load The TPS799 is stable with no output load. To meet the specified accuracy, a minimum load of 500 μA is required. With loads less than 500 μA at junction temperatures near 125°C, the output can drift up enough to cause the output pulldown device to turn on. The output pulldown device limits voltage drift to 5% typically; however, ground current can increase by approximately 50 μA. In typical applications, the junction cannot reach high temperatures at light loads because there is no noticeable dissipated power. The specified ground current is then valid at no load in most applications. 8.2.2.6 Feedback Capacitor Requirements (TPS79901 Only) The feedback capacitor, CFB, shown in Figure 29 is required for stability. For a parallel combination of R1 and R2 equal to 250 kΩ, any value from 3 pF to 1 nF can be used. Fixed voltage versions have an internal 30-pF feedback capacitor which is quick-charged at start-up. The adjustable version does not have this quick-charge circuit, so values below 5 pF should be used to ensure fast startup; values above 47 pF 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.

Power-Supply Rejection Ratio vs Frequency 8.3 Do's and Don'ts Do place at least one 2.2-µF ceramic capacitor as close as possible to the OUT pin of the regulator. Do not place the output capacitor more than 10 mm away from the regulator. Do connect a 0.1-μF to 1-μF low equivalent series resistance (ESR) capacitor across the IN pin and GND input of the regulator. Do not exceed the absolute maximum ratings. 9 Power Supply Recommendations These devices are designed to operate from an input voltage supply range between 2.7 V and 6.5 V. The input voltage range provides adequate headroom in order for the device to have a regulated output. This input supply is well-regulated and stable. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance. 10 Layout 10.1 Layout Guidelines 10.1.1 Board Layout Recommendations to Improve PSRR and Noise Performance To improve ac performance (such as PSRR, output noise, and transient response), design the board with separate ground planes for VIN and VOUT, with each ground plane connected only at the GND pin of the device. In addition, connect the bypass capacitor directly to the GND pin of the device. 16 Submit Documentation Feedback Copyright © 2005–2015, Texas Instruments Incorporated Product Folder Links: TPS799 TPS799 www.ti.com SBVS056K – JANUARY 2005 – REVISED JANUARY 2015 10.2 Layout Example VI VO TPS799 CIN COUT EN GND CNR Represents via used for application specific connections. Figure 31. Layout Example 10.3 Thermal Information 10.3.1 Thermal Protection 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 resulting from overheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink. For reliable operation, limit junction temperature 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 triggers at least 35°C above the maximum expected ambient condition of a particular application. This configuration produces a worst-case junction temperature of 125°C at the highest expected ambient temperature and worst-case load. The internal protection circuitry of the TPS799 is designed to protect against overload conditions. This circuitry is not intended to replace proper heatsinking. Continuously running the device into thermal shutdown degrades device reliability. 10.3.2 Power Dissipation 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 Thermal Information table near the front of this data sheet. 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 is equal to the product of the output current times the voltage drop across the output pass element, as shown in Equation 2: P D + ǒVIN*V OUTǓ @ I OUT (2) 10.3.3 Package Mounting Solder pad footprint recommendations for the TPS799 are available from the TI's website at www.ti.com.
