When setting VOUT to a value other than 0.5 V, connect R2 to the FB pin using 27-kΩ ≤ R2 ≤ 33-kΩ resistors. See Figure 7 for details of
R1 and R2.
Accuracy does not include error on feedback resistors R1 and R2.
TPS7A7002 is not tested at VOUT = 0.5 V, 2.3 V ≤ VIN ≤ 6.5 V, and 500 mA ≤ IOUT ≤ 3 A because the power dissipation is higher than
the maximum rating of the package. Also, this accuracy specification does not apply to any application condition that exceeds the power
dissipation limit of the package.
VIN = VOUT + 0.5 V or 1.425 V, whichever is greater.

The TPS7A7002 offers a high current supply with very-low dropout voltage. The TPS7A7002 is designed to
minimize the required component count for a simple, small-size, and low-cost solution.

7.3 Feature Description
7.3.1 Internal Current Limit
The TPS7A7002 internal current limit helps protect the regulator during fault conditions. During a current limit
condition, the output sources a fixed amount of current largely independent of output voltage. For reliable
operation, do not operate the device in a current limit state for an extended period of time.
Powering on the device with the enable pin, or increasing the input voltage above the minimum operating voltage
while a low-impedance short exists on the output of the device, may result in a sequence of high-current pulses
from the input to the output of the device. The energy consumed by the device is minimal during these events;
therefore, there is no failure risk. Additional input capacitance helps to mitigate the load transient requirement of
the upstream supply during these events.
7.3.2 Enable (EN)
The enable pin (EN) is an active-high logic input. When it is logic low, the device turns off, and the consumption
current is less than 1 µA. When it is logic high, the device turns on. The EN pin must be connected to a logic
high or logic low level.
When the enable function is not required, connect EN to IN.

7.4.1 Normal Operation
The device regulates to the nominal output voltage under the following conditions:
• The input voltage is greater than the nominal output voltage plus the dropout voltage (VOUT(nom) + VDO).
• The enable voltage has previously exceeded the enable rising threshold voltage and not yet decreased below
the enable falling threshold.
• The output current is less than the current limit (IOUT < ICL).
• The device junction temperature is less than the thermal shutdown temperature (TJ < TSD).
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 mode, the output voltage
tracks the input voltage. During this mode, the transient performance of the device becomes 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.

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 TPS7A7002 offers a high current supply with very-low dropout voltage, and it is designed to minimize the
required component count for a simple, small-size, and low-cost solution. This section discusses the
implementation of the TPS7A7002 LDO.
8.1.1 Input Capacitor (IN)
An input capacitor is not required for stability; however, TI recommends connecting a 1-µF to 10-µF low
equivalent series resistance (ESR) capacitor across IN and GND as close as possible to the device.
8.1.2 Output Capacitor (OUT)
The TPS7A7002 is stable with standard ceramic capacitors with capacitance values from 4.7 μF to 47 μF without
a feedforward capacitor. For output capacitors from 47 μF to 200 μF, a feedforward capacitor of at least 220 pF
must be used. The TPS7A7002 is evaluated using an X5R-type, 10-μF ceramic capacitor. X5R- and X7R-type
capacitors are recommended because of minimal variation in value and ESR over temperature. Maximum ESR
must be less than 1 Ω.
As with any regulator, increasing the size of the output capacitor reduces overshoot and undershoot magnitude,
but increases duration of the transient response.
8.1.3 Feedback Resistors (FB)
The voltage on the FB pin sets the output voltage and is determined by the values of R1 and R2. Use Equation 1
to calculate the values of R1 and R2 for any voltage.

Table 2 shows the recommended resistor values for the best performance of the TPS7A7002. If the values in
Table 2 are not used, keep the value of R2 from 27 kΩ to 33 kΩ. In Table 2, E96 series resistors are used. For
the actual design, pay attention to any resistor error factors.

8.2 Typical Application
This section describes the implementation of the TPS7A7002, using the feedback pin to configure the output
voltage and regulate a 2-A load at 1.4 V using a 1.6-V input voltage, operating in a temperature range of 25°C to
85°C. Figure 8 shows the schematic for this typical application circuit.

8.2.2 Detailed Design Procedure
At IOUT = 2 A, the TPS7A7002 has a maximum dropout of less than 150 mV over temperature, as seen in
Figure 9; thus, a 200-mV headroom is sufficient for operation over both input and output voltage accuracy.
To achieve 1.2 V on the output, choose the correct feedback resistors. The Feedback Resistors (FB) section
suggests keeping the value of R2 in the range of 27 kΩ to 33 kΩ, so select R2 to be 30.1 kΩ, a standard resistor
in the E96 series. Using Equation 1 to achieve a 1.4-V output, determine the size for R1 using Equation 2.
R1 = ((2 × VOUT) – 1) × R2
(2)
Given that R2 = 30.1 kΩ and VOUT = 1.4 V, R1 = 54.2 kΩ. The closest resistor in the E96 series is 53.6 kΩ, giving
an output voltage within the output design requirements.
With a headroom voltage of 200 mV and a 2-A maximum load, the internal power dissipation is 400 mW, and
corresponds to a 18.56°C junction temperature rise for the DDA package.
With a 75°C maximum ambient temperature as per design constraints, the junction temperature is at 93.56°C,
and satisfies the recommended operating junction temperature range.

9 Power Supply Recommendations
These devices are designed to operate from an input voltage supply range from 1.425 V to 6.5 V. The input
voltage range provides adequate headroom 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
For best performance, place all circuit components on the same side of the circuit board, and place the external
components as close to the device as practically possible. The use of vias and long traces is strongly
discouraged because of parasitics that might affect performance; follow these guidelines to minimize parasitics.
Also, embed a ground reference plane to maintain accuracy of the output voltage and shield noise. Make sure
that this plane is connected to the PowerPAD in order to help spread (or sink) heat from the device; be aware
that NC pins might be connected to this plane. The recommended layout is shown in Figure 10.

10.3 Thermal Consideration
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 re-enabled.
The internal protection circuitry of the TPS7A7002 is designed to protect against overload conditions. The
protection circuitry is not intended to replace proper heat sinking. Continuously running the TPS7A7002 into
thermal shutdown degrades device reliability.
10.4 Power Dissipation
Power dissipation (PD) of the device depends on the input voltage and load conditions, and is calculated using
Equation 3.

VIN VOUT u IOUT

In order to minimize power dissipation and achieve greater efficiency, use the lowest possible input voltage
necessary to achieve the required output voltage regulation
On the SOIC (DDA) package, the primary conduction path for heat is through the exposed pad to the PCB. The
pad can either be connected to ground or left floating; however, attach the pad to an appropriate amount of
copper PCB area to prevent the device from overheating. The maximum junction-to-ambient thermal resistance
depends on the maximum ambient temperature, maximum device junction temperature, and power dissipation of
the device, and is calculated using Equation 4:
