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. 7.2 Functional Block Diagram CS VIN 1.2 V 2 mA EN ISS Thermal Protection OCP RTOP PCL RBOT VREF 1.1*VREF PG 0.9*VREF 12 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TPS7H1101A-SP TPS7H1101A-SP www.ti.com SLVSDW6C – APRIL 2017 – REVISED APRIL 2021 7.3 Feature Description 7.3.1 Soft Start Connecting a capacitor (CSS) from the SS terminal to GND slows down the output voltage ramp rate. The soft-start capacitor charges up to 1.2 V, with a threshold of VFB. tSS · ISS CSS = ¾ VFB (1) where • • • tss = soft-start time Iss = 2.5 µA VFB = VREF = 0.605 V 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.

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. Signal injection TPS7H1101A-SP IN OUT 50Ÿ VIN + ± RESR RESR CCOMP gm COMP RLOAD RT COUT CIN FB RB 0.6V VREF 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. 14 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TPS7H1101A-SP TPS7H1101A-SP www.ti.com SLVSDW6C – APRIL 2017 – REVISED APRIL 2021 8.2 Typical Application TPS7H1101A-SP Power Good 5V VIN CIN RCS COMP EN RT PCL RPCL Soft Start CSS 3.3 V VOUT CS GND COUT Feed Back RB Copyright © 2017, Texas Instruments Incorporated Figure 8-2.

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. 16 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TPS7H1101A-SP TPS7H1101A-SP www.ti.com SLVSDW6C – APRIL 2017 – REVISED APRIL 2021 The maximum PCL is 3.5 A.

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.

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.

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. 1 Fp_co = 2¾ ·p·Co·RL (6) 1 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. 1 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.

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.

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. 10.2 Layout Example R C R EN 3 VIN 4 VIN 5 VIN 6 VIN 7 PCL 8 GND 16 COMP 15 VOUT 14 VOUT 13 VOUT 12 VOUT 11 CS 10 PG/OC Cap C Vout plane Cap Cap R R To CS sense 2 FB R VIN plane SS TPS7H1101A-SP Cap R Cap 1 9 To PG/OC sense Main GND layer(s) plane Vias from top layer thermal pad GND to main GND plane(s) Via to GND Figure 10-1.
