TPS717
SBVS068I – FEBRUARY 2006 – REVISED JANUARY 2016
TPS717
Low-Noise, High-Bandwidth PSRR, Low-Dropout, 150-mA Linear Regulator
1 Features
3 Description
•
•
The TPS717 family of low-dropout (LDO), low-power
linear regulators offers very high power-supply
rejection (PSRR) while maintaining very low 45-μA
ground current in an ultra-small, five-pin SOT
package. The family uses an advanced BiCMOS
process and a PMOS pass device to achieve fast
start-up, very low noise, excellent transient response,
and excellent PSRR performance. The TPS717 is
stable with a 1-μF ceramic output capacitor and uses
a precision voltage reference and feedback loop to
achieve a worst-case accuracy of 3% over all load,
line, process, and temperature variations. The device
family is fully specified from TJ = –40°C to 125°C and
is offered in a small SOT (SC70-5) package, a
2-mm × 2-mm WSON-6 package with a thermal pad,
and a 1.5-mm × 1.5-mm WSON-6 package, which
are ideal for small form factor portable equipment
(such as wireless handsets and PDAs).

7 Detailed Description
7.1 Overview
The TPS717 family of low-dropout (LDO) regulators combines the high performance required by many RF and
precision analog applications with ultra-low current consumption. High PSRR is provided by a high-gain, highbandwidth error loop with good supply rejection with very low headroom (VIN – VOUT). Fixed voltage versions
provide a noise reduction pin to bypass noise generated by the band-gap reference and to improve PSRR. A
quick-start circuit fast-charges this capacitor at startup. The combination of high performance and low ground
current also make the TPS717 family of devices an excellent choice for battery-powered applications. All
versions have thermal and overcurrent protection.

7.3 Feature Description
7.3.1 Internal Current Limit
The TPS717 internal current limit helps protect the regulator during fault conditions. During current limit, the
output sources a fixed amount of current that is largely independent of 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 TPS717 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.
7.3.2 Shutdown
The enable pin (EN) is active high and compatible with standard and low voltage, TTL-CMOS levels. When
shutdown capability is not required, EN can be connected to IN.
7.3.3 Startup and Noise Reduction Capacitor
Fixed voltage versions of the TPS717 use a quick-start circuit to fast-charge the noise reduction capacitor, CNR, if
present (see Figure 31). This circuit 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, apply VIN first, then drive the enable pin high. If EN is tied to IN, startup is somewhat
slower. The quick-start switch is closed for approximately 135 μs. To ensure that CNR is fully charged during the
quick-start time, use a 0.01-μF or smaller capacitor.

Feature Description (continued)
For output voltages below 1.6 V, a voltage divider on the band-gap reference voltage is employed to optimize
output regulation performance for lower output voltages. This configuration results in an additional resistor in the
quick-start path and combined with the noise reduction capacitor (CNR) results in slower start-up times for output
voltages below 1.6 V.
Equation 1 approximates the start-up time as a function of CNR for output voltages below 1.6 V:
ms
tSTART = 160ms + (540
x CNRnF)ms
nF
(1)
7.3.4 Undervoltage Lockout (UVLO)
The TPS717 uses an undervoltage lockout circuit to keep the output shut off until the internal circuitry is
operating properly. The UVLO circuit has a limited glitch immunity so undershoot transients are typically ignored
on the input if these transients are less than 5 μs in duration. When the input is lower than 1.4 V, the UVLO
circuit may not have enough headroom to keep the output fully off.
7.3.5 Minimum Load
The TPS717 is stable with no output load. Traditional PMOS LDO regulators suffer from lower loop gain at very
light output loads. The TPS717 employs an innovative low-current mode circuit to increase loop gain under very
light or no-load conditions, resulting in improved output voltage regulation performance down to zero output
current.
7.3.6 Thermal Protection
Thermal protection disables the output when the junction temperature rises to approximately 160°C, allowing the
device to cool. When the junction temperature cools to approximately 140°C the output circuitry is again enabled.
Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit can
cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage because of
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, trigger thermal protection at least 35°C
above the maximum expected ambient condition of a particular application. This configuration produces a worstcase junction temperature of 125°C at the highest expected ambient temperature and worst-case load.
The internal protection circuitry of the TPS717 is designed to protect against overload conditions. This circuitry is
not intended to replace proper heatsinking. Continuously running the TPS717 into thermal shutdown degrades
device reliability.

Device Functional Modes (continued)
7.4.2 Dropout Operation
If the input voltage is lower than the nominal output voltage plus the specified dropout voltage, but all other
conditions are met for normal operation, the device operates in dropout mode. In this condition, the output
voltage is the same as the input voltage minus the dropout voltage. The transient performance of the device is
significantly degraded because the pass device is in a triode state and no longer controls the current through the
LDO. Line or load transients in dropout can result in large output voltage deviations.
7.4.3 Disabled
The device is disabled under the following conditions:
• The input voltage is less than the UVLO falling voltage, or has not yet exceeded the UVLO rising threshold.
• The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising
threshold.
• The device junction temperature is greater than the thermal shutdown temperature.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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 TPS717 belongs to a family of new generation LDO regulators that use innovative circuitry to achieve ultrawide bandwidth and high loop gain, resulting in extremely high PSRR at very low headroom (VIN – VOUT). Fixed
voltage versions provide a noise reduction pin to bypass noise generated by the band-gap reference and to
improve PSRR when a quick-start circuit fast-charges this capacitor. These features, combined with low noise,
enable, low ground pin current, and ultra-small packaging, make this part ideal for many applications. This family
of regulators offers sub-band-gap output voltages, current limit, and thermal protection, and is fully specified from
–40°C to 125°C.
8.1.1 Transient Response
As with any regulator, increasing the size of the output capacitor reduces overshoot or undershoot magnitude but
increases duration of the transient. The TPS717 has an ultra-wide loop bandwidth that allows it to respond
quickly to load transient events. As with any regulator, the loop bandwidth is finite and the initial transient voltage
peak is controlled by the sizing of the output capacitor. Typically, larger output capacitors reduce the peak and
also reduce the bandwidth of the LDO, thus slowing the response time.
8.1.2 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 or
larger low equivalent series resistance (ESR) capacitor from IN to GND 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.
The TPS717 is designed to be stable with ceramic output capacitors of values 1 μF or larger. The X5R- and
X7R-type capacitors are best because they have minimal variation in value and ESR over temperature. The
maximum ESR of the output capacitor must be less than 1 Ω. The minimum output capacitance is increased to
5 μF or larger if using an R2 value outside of the range of 160 kΩ to 320 kΩ.
8.1.3 Dropout Voltage
The TPS717 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
RDSon of the PMOS pass element. VDO scales approximately with output current because the PMOS device
functions as a resistor in dropout.
As with any linear regulator, PSRR and transient response are degraded when (VIN – VOUT) approaches dropout.
This effect is illustrated in Figure 15 through Figure 17 in the Typical Characteristics section.

Application Information (continued)
8.1.4 Output Noise
In most LDOs, the band gap is the dominant noise source. If a noise reduction capacitor (CNR) is used with the
TPS717, 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 (minimum)
noise reduction capacitor; for the adjustable version, smaller value resistors in the output resistor divider reduce
noise. A parallel combination that gives 2.5 μA of divider current has the same noise performance as a fixed
voltage version.

8.3 Do's and Don'ts
Do place at least one 1-µF ceramic capacitor as close as possible in the range of the regulator.
Do not place the output capacitor more than 10 mm away from the regulator.
Do not place any components in the feedback loop except for the output capacitor and feedback resistors.
Do not exceed the device absolute maximum ratings.
Do not float the enable (EN) pin.
9 Power Supply Recommendations
The TPS717 is designed to operate from an input voltage between 2.5 V and 6.5 V. The input supply must
provide adequate headroom for the device to operate in a normal mode of operation.
Connect a low output impedance power supply directly to the IN pin of the TPS717. Inductive impedances
between the input supply and the IN pin can create significant voltage excursions at the IN pin during startup or
load transient events. If inductive impedances are unavoidable, use an input capacitor. To increase the overall
PSRR of the power solution, use a pi-filter before the input of the LDO or after the feedback network of the LDO.

10 Layout
10.1 Layout Guidelines
For best overall performance, place all circuit components on the same side of the circuit board and as near as
practical to the respective LDO pin connections. Place ground return connections to the input and output
capacitor, and to the LDO ground pin as close to the GND pin as possible, connected by wide, component-side,
copper surface area. The use of vias and long traces to create LDO component connections is strongly
discouraged and negatively affects system performance. This grounding and layout scheme minimizes inductive
parasitics, and thereby reduces load-current transients, minimizes noise, and increases circuit stability. A ground
reference plane is also recommended and is either embedded in the printed circuit board (PCB) itself or located
on the bottom side of the PCB opposite the components. This reference plane serves to assure accuracy of the
output voltage, shields the LDO from noise, and functions similar to a thermal plane to spread (or sink) heat from
the LDO device when connected to the thermal pad. In most applications, this ground plane is necessary to meet
thermal requirements.
10.1.1 Board Layout Recommendations to Improve PSRR and Noise Performance
To improve ac performance (such as PSRR, output noise, and transient response), TI recommends 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 must connect directly to the
GND pin of the device.

10.3 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. Performance data for JEDEC low- and high-K boards are given in the
Thermal Information table. Using heavier copper increases the effectiveness in removing heat from the device.
The addition of plated through-holes to heat-dissipating layers also improves the heatsink effectiveness.
Power dissipation depends on input voltage and load conditions. Power dissipation (PD) is equal to the product of
the output current times the voltage drop across the output pass element (VIN to VOUT), and is approximated in
Equation 4:
PD
VIN VOUT u IOUT

Power Dissipation (continued)
A better method of estimating the thermal measure comes from using the thermal metrics ΨJT and ΨJB; see the
Thermal Information table. These metrics are a more accurate representation of the heat transfer characteristics
of the die and the package than RθJA. The junction temperature can be estimated with Equation 5.
YJT: TJ = TT + YJT · PD
YJB: TJ = TB + YJB · PD
where
•
•
•
PD is the power dissipation given by Equation 4,
TT is the temperature at the center-top of the device package,
TB is the PCB temperature measured 1 mm away from the device package on the PCB surface.
(5)
NOTE
Both TT and TB can be measured on actual application boards using a thermo-gun (an
infrared thermometer).
For more information about measuring TT and TB, see the application note Using New Thermal Metrics
(SBVA025), available for download at www.ti.com.

TPS717xx(x)yyyz
xx(x) is the nominal output voltage. For output voltages with a resolution of 100 mV, two digits are used
in the ordering number; otherwise, three digits are used (for example, 28 = 2.8 V; 125 = 1.25 V). An 01
denotes an adjustable voltage version.
yyy is the package designator.
z is the package quantity. R is for a large reel (3000 pieces), T is for a small reel (250 pieces).
