7 Detailed Description
7.1 Overview
The TPS7H1101A-SP is 3-A, 1.5-V to 7-V LDO linear regulator that uses PMOS pass element configuration.
It uses TI’s proprietary process to achieve low noise, high PSRR combined with high-thermal performance in a
16-pin ceramic flatpack package (HKR).
A number of features are incorporated in the design to provide high reliability and system flexibility. Current
foldback, current limit, and thermal protection are incorporated in the design to make it viable for space
environments.
The device also has a current sense monitoring feature. A resistor connected from the current sense (CS)
terminal to VIN indicates voltage proportional to the output current. Section 8.2.1.3 provides a detailed
description of this feature. When CS is pulled high to voltage greater than 90% Vref (0.544 V), foldback current
limit is enabled. Pulling CS below 0.544 V disables the foldback current limit.
A resistor connected from the programmable current limit (PCL) terminal to ground sets the overcurrent limit
activation point. When overcurrent limit activation point is reached, it results in the LDO going into current
foldback mode. Output current is reduced to approximately 50% of the current limit set point. Section 8.2.1.2
provides a detailed description of this feature.
TPS7H1101A-SP incorporates thermal protection, which disables the output when the junction temperature rises
to approximately 185°C, allowing the device to cool. Cycling limits the dissipation of the regulator, protecting it
from catastrophic damage as a result of overheating.
To provide system flexibility for demanding current needs, the LDO can be configured in parallel operation as
indicated in Figure 8-12. Section 8.2.1.6 provides detailed parallel operation information.
An enable feature is incorporated in the design allowing the user to enable or disable the LDO. Power
Good (PG), is an open-drain connection, indicating status of the output voltage regulation. These provide the
customers system flexibility in monitoring and controlling the LDO operation.

7.3.2 Power Good (PG)
Power Good terminal (9) is an open-drain connection and can be used to sequence multiple LDOs. Figure
7-1 shows typical connection. The PG terminal will be pulled low until the output voltage reaches 90% of its
maximum level. At that point, the PG pin will be pulled up. Since the PG pin is open drain, it can be pulled up to
any voltage as long as it does not exceed the absolute max of 7.5 V listed in Section 6.5.

7.4.1 Enable/Disable
For VIN from 1.5 V to 7 V, TPS7H1101A-SP can be disabled by pulling the enable terminal to logic low at a
minimum of 0.7 V. Enable cannot exceed VIN by more than 0.3 V, and in most cases, the enable terminal is
connected to VIN.

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, as well as validating and testing their design
implementation to confirm system functionality.
8.1 Application Information
The TPS7H1101A-SP LDO linear regulator is targeted space environment applications. This regulator has
various features such as low dropout, soft start, output current foldback, high-side current sensing (where
sensing voltage at CS pin provides voltage proportional to output current), and current sharing.
8.1.1 Stability
Bode plots are a standard approach in assessing stability. This approach requires a single feedback path
where an AC signal is injected across a resistor (typically 50 Ω) and measurements are taken on either side
of the resistor as shown in Figure 8-1. From this measurement, loop gain and phase plots can be generated.
Crossover frequency, ƒC, is defined as the frequency where the magnitude of the loop gain is unity and phase
margin is evaluated at the crossover frequency ƒC.

Figure 8-1. Conventional Bode Plot With Simplified Feedback Loops
However, it is important the AC signal is injected as shown in Figure 8-1. This injection point ensures that the
feedback signal goes through both the outer loop (consisting of the top feedback resistor, RT) and the inner loop
(consisting of the compensation capacitor, CCOMP). If the only the outer loop is measured, the resulting crossover
frequency will be lower which would indicate a poorer transient response than reality. Therefore, it is best to
inject the measurement signal at a point where it goes through both loops. If this is not possible, the two loops
may be measured independently and added using the superposition principle.
Furthermore, the stability of the device can be qualitatively validated by applying a step load to the output and
observing the response. The SPICE models for the device can be found on the TPS7H1101A-SP product page.
To simulate impedance measurements, the transient model should be used.

8.2.1.1 Adjustable Output Voltage (Feedback Circuit)
The output voltage of the TPS7H1101A-SP can be set to a user-programmable level between 0.8 V and 6.65
V. Achieve this by using a resistor divider connected between VOUT, FB, and GND terminals. RTOP connected
between VOUT and VFB, and RBOTTOM connected between VFB and GND.

where
•
•
•
•
VREF = 0.605 V
ICL = Programmable current limit (A)
Current sense ratio (CSR) is the ratio of output load current to ICS; typical value of the CSR is 52000
Offset value 0.0403 is a fixed offset derived from internal keep-alive biasing
Figure 8-3 shows the output load current (ILOAD) versus PCL terminal current (IPCL) varied with minimum and
maximum range of CSR values by temperature. The RPCL resistor should be chosen to set the worst case ILOAD
across system normal operating load and temperature range without reaching overcurrent activation point of IPCL
· RPCL ≥ VREF.
Additionally, a suitable resistor RCS must be chosen to ensure the CS terminal is within its operating range of 0.3
V to VIN and VCS needs to be greater than 0.9 · VREF (0.544 V) to insure foldback remains enabled when current
activation point is triggered.

The maximum PCL is 3.5 A. The range of resistor that can be used on the PCL terminal to GND is 8.2 kΩ to 160
kΩ. It is not recommended to use overcurrent limit activation thresholds of less than 500 mA due to internal bias
offset currents representing a larger percentage of total IPCLcurrent and therefore additional error.

8.2.1.4 Current Foldback
1. The TPS7H1101A-SP has a current foldback feature which can be enabled when the CS terminal is greater
than 0.9 · VREF (0.544 V). Pulling CS below this threshold disables the foldback current limit. If the foldback
current limit is disabled, then the LDO will begin regulating again as soon as the current falls below the
clamp threshold.
2. With foldback current limit enabled, when current limit trip point is activated,
a. Output voltage drops low, and
b. Output current folds back to approximately 50% of the current limit trip point.
This results in minimizing the power loss under fault conditions. Monitoring the voltage at the CS terminal
indicates voltage proportional to the output current. It is important to note that the current sense voltage
range on CS pin must be designed to stay above the 0.9 · VREF threshold to insure foldback is not
inadvertently disabled at high currents.

8.2.1.6 Current Sharing
For demanding load requirements, multiple LDOs can be paralleled as indicated in Figure 8-12. In parallel mode,
the CS terminal of LDO1 must be connected to the PCL terminal of LDO2 via a series resistor, RCL, and CS
terminal of LDO2 must be connected to PCL terminal of LDO1 via series resistor, RCL. The typical value of RCL
in parallel operation is 3.75 kΩ for current limit > 6 A. In parallel configuration, RCL (resistor from PCL to GND)
and RCS (resistor from CS terminal to VIN) must be left open (unpopulated). The RCL value must be selected so
that the operating condition of the CS terminal is maintained, as specified in Section 6.5. VCS must be greater
than 0.3 V to insure proper current sense operation. The current from PCL through RCL of LDO1 is determined
by the output load current of LDO2 divided by the CSR. Hence, the voltage at CS terminal of the LDO1 is 0.605
V – ((output load current of LDO2 + 0.2458) / CSR × RCL).
Alternately, it can also provide twice the output current to meet system needs. When using two LDOs in parallel
operation for higher output load current, use POL TPS50601-SP as an input source.

Figure 8-13. TPS7H1101A-SP Compensation
Resistor divider composed of Rtop and Rbottom determine the output voltage set points as indicated by Equation
2.
Output capacitor COUT introduces a pole and a zero as shown in the following.

Fp_co = 2¾
·p·Co·RL

Fz_co = 2¾
·p·Co·Cesr
(7)
The TPS7H1101A-SP was designed so that the ESR of the output capacitor will not have a strong influence on
the response of the LDO. However, an optional capacitor, Cx, can be added in parallel with the bottom feedback
resistor to introduce a pole to cancel Fz_co. Equation 8 shows how to calculate the location of the pole introduced
by Cx. To cancel the zero directly, Fp should be equal to Fz_co.

Fp = 2¾
·p·Cx·Rbottom
(8)
Cx is calculated to be 1000 pF for Co = 220 µF, Cesr = 45 mΩ, and Rbottom = 10 kΩ.
Figure 8-13 also includes a place holder for a feed forward capacitance Cff. Use of feed forward compensation
can be more advantageous than use of Cx. Please reference application note Pros and Cons of Using a
Feedforward Capacitor with a Low-Dropout Regulator for additional information on usage of CFF.
Internal compensation in the LDO cancels the output capacitor pole introduced by COUT and RL.
Ccomp introduces a dominant pole at low frequency. TI recommends that a Ccomp value of 10 nF.
8.2.1.8 Output Noise

8.2.1.9 Capacitors
TPS7H1101A-SP requires the use of a combination of tantalum and ceramic capacitors to achieve good volume
to capacitance ratio. Table 8-2 highlights some of the capacitors used in the device. TI recommends to follow
proper derating guidelines as recommended by the capacitor manufacturer based upon output voltage and
operating temperature.
Note that polymer-based tantalum capacitors must be derated to at least 60% of rated voltage, whereas
manganese oxide (MnO2) based tantalum capacitors should be derated to 33% of rated voltage depending
upon the operating temperature.
TI recommends to use a tantalum capacitor along with a 0.1-µF ceramic capacitor. The device is stable for input
and output tantalum capacitor values of 10 µF to 220 µF with the ESR range of 10 mΩ to 2 Ω. However, the
dynamic performance of the device varies based on load conditions and the capacitor values used.
TI recommends a minimum output capacitor of 22 µF with ESR of 1 Ω or less to prevent oscillations. X7R
dielectrics are preferred. See Table 8-2 for various capacitor recommendations.

9 Power Supply Recommendations
This device is designed to operate with an input voltage supply up to 7 V. The minimum input voltage should
provide adequate headroom greater than the dropout voltage for the device to have a regulated output. 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, all traces should be as short as possible, and no longer than 5 cm.
Use wide traces for IN, OUT and GND to minimize the parasitic electrical effects.
Place the output capacitors (COUT) as close as possible to the OUT pin of the device.
