(Note 4) Applicable for product with BD9xxN1WG-C, BD9xxN1WEFJ-C (xx = 33, 50, 00) (Note 5) If the inductance of power supply line is high, please adjust input capacitor value in order to lower the input impedance. A lower input impedance can bring out the ideal characteristic of IC as much as possible. It also has the effect of preventing the voltage-drop at the input line. (Note 6) Set capacitor value which do not fall below the minimum value. This value needs to consider the temperature characteristics a nd DC device characteristics. For applications where the output voltage is 1.5 V or less, it is recommended to use an output capacitor of 0.22 μF or more because the output capacitor holds less charge, increasing the amount of voltage fluctuation during transient response . (Note 7) It is recommended to use ceramic capacitors that have low ESR characteristics for output phase compensation. In case of using electrolytic capacitor or ceramic capacitor with large ESR (>500 mΩ), note that ceramic capacitor with 0. 05μF and more must be connected near VOUT pin in parallel.

Therefore, it does not guarantee its operation on the specific function , accuracy or external components in the application. In the application, it shall be designed with sufficient margin by enough understanding about characteristics of the external components, e.g. capacitor, and also by appropriate verification in the actual operating conditions. Selection of External Components Input Pin Capacitor In order to fully demonstrate the performance of this IC, it is recommended that the input capacitor be placed as close as possible to the input pin and the GND pin without being affected by mounting impedance, etc., and that it be laid out on the same mounting surface. In this case, a capacitor with a capacitance value of 0.047 μF (Min) or higher is recommended. Depending on the layout of the peripheral components, including this IC, from the input power supply, if the distance from the battery is too far or the impedance of the input side is too high, for example, the current supply due to the load response of the IC cannot be withstood, and the output voltage may become unstable due to fluctuations in the input voltage. In such a case, it is necessary to use a large capacitor to prevent the line voltage from dropping. Select the capacitance of the input terminal capacitor according to the line impedance between the power smoothing circuit and the input terminal, and the load response required by the application. In addition, the consideration should be taken as the output pin capacitor, to prevent an influence to the regulator ’s characteristic from the deviation or the variation of the external capacitor ’s characteristic. All output capacitors mentioned above are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %, e.g. X7R, X8R) with being satisfied high absolute maximum voltage rating based on EIA standard. These capacitors should be placed close to the inpu t pin and mounted on the same board side of the regulator not to be influenced by implement impedance. Output Pin Capacitor The output capacitor is mandatory for the regulator i n order to realize stable operation. The output capacitor with capacitance value of 0.05 μF (Min) or higher and ESR up to 500 mΩ (Max) must be required between the output pin and the GND pin. For applications where the output voltage is 1.5 V or less, it is recommended to use an output capacitor with capacitance value of 0.22 μF or higher because the output capacitor holds less charge, increasing the amount of voltage fluctuation during transient response. A proper selection of appropriate both the capacitance value and ESR for the output capacitor can improve the transient behavior of the regulator and can also keep the stability with better regulation loop. The correlation of the output capacitance value and ESR is shown in the graph on the next page as the output capacitor’s capacitance value and the stability region for ESR. As described in this graph, this regulator is designed to be stable with ceramic capacitors as of MLCC, with the capacitance value from 0.05 μF to 470 μF and with ESR value within almost 0 Ω to 500 mΩ. The frequency range of ESR can be generally considered as within about 10 kHz to 100 kHz. Note that the provided the stable area of the capacitance value and ESR in the graph is obtained under a specific set of conditions which is based on the measurement result in single IC on our board with a resistive load. I n the actual environment, the stability is affected by wire impedance on the board, input power supply impedance and also loads impedance. Therefore, please note that a careful evaluation of the actual application , the actual usage environment and the actual conditions should be done to confirm the actual stability of the system. Generally, in the transient event which is caused by the input voltage fluctuation or the load fluctuation beyond the gain bandwidth of the regulation loop, the transient response ability of the regulator depends on the capacitance value of the output capacitor. Basically the capacitance value of 0.05 μF (Min) or higher for the output capacitor is recommended as shown in the table on Output Capacitance COUT, ESR Available Area. Using bigger capacitance value can be expected to improve better the transient response ability in a high frequency. Various types of ca pacitors can be used for the output capacitor with high capacity which includes electrolytic capacitor, electro -conductive polymer capacitor and tantalum capacitor. Noted that, depending on the type of capacitor s, its characteristics such as ESR (≤ 500 mΩ) absolute value range, a temperature dependency of capacitance value and increased ESR at cold temperature needs to be taken into consideration. When using capacitor with large ESR (≤500m Ω) , note that ceramic capacitor with 0.05 uF or higher must be connected in parallel to keep stability. In this case, the total capacitance should be less than 470 µF. In addition, the same consideration should be taken as the input pin capacitor, to prevent an influence to the regulator ’s characteristic from the deviation or the variation of the external capacitor ’s characteristic. All output capacitors mentioned above are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %, e.g. X7R, X8R) with being satisfied high absolute maximum voltage rating based on EIA standard. These capacitors should be placed close to the output pin and mounted on the same board side of the regulator not to be influenced by implement impedance.

The power consumption of the IC is decided by the dropout voltage condition, the load current and the current consumption. Refer to power dissipation curves illustrated in Figure 62 and 63 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at 25°C, chip junction temperature (Tj) can be very high depending on the input voltage and the load current. Consider the design to be Tj ≤ Tjmax = 150 °C in whole operating temperature range. Should by any condition the maximum junction temperature Tjmax = 150 °C rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Therefore, need to be careful because it might be different from the actual use condition. Verify the application and allow sufficient margins in the thermal design by the following method to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods. 1. The following method is used to calculate the junction temperature Tj with ambient temperature Ta. 𝑇𝑗 = 𝑇𝑎 + 𝑃𝐶 × 𝜃𝐽𝐴 [°C] Where: Tj is the Junction Temperature Ta is the Ambient Temperature PC is the Power Consumption θJA is the Thermal Resistance (Junction to Ambient) 2. The following method is also used to calculate the junction temperature Tj with top center of case’s (mold) temperature TT. 𝑇𝑗 = 𝑇𝑇 + 𝑃𝐶 × 𝛹𝐽𝑇 [°C] Where: Tj is the Junction Temperature TT is the Top Center of Case’s (mold) Temperature PC is the Power consumption ΨJT is the Thermal Resistance (Junction to Top Center of Case) 3. The following method is used to calculate the power consumption Pc (W). 𝑃𝑐 = (𝑉𝐼𝑁 − 𝑉𝑂𝑈𝑇) × 𝐼𝑂𝑈𝑇 + 𝑉𝐼𝑁 × 𝐼𝐶𝐶 [W] Where: PC is the Power Consumption VIN is the Input Voltage VOUT is the Output Voltage IOUT is the Load Current ICC is the Current Consumption

Calculation Example (HTSOP-J8) If VIN = 13.5 V, VOUT = 5.0 V, IOUT = 40 mA, ICC = 28 μA, the power consumption Pc can be calculated as follows: 𝑃𝐶 = (𝑉𝐼𝑁 − 𝑉𝑂𝑈𝑇) × 𝐼𝑂𝑈𝑇 + 𝑉𝐼𝑁 × 𝐼𝐶𝐶 = (13.5 𝑉 – 5.0 𝑉) × 40 𝑚𝐴 + 13.5 𝑉 × 28 𝜇𝐴 = 0.34 𝑊 At the maximum ambient temperature Tamax = 85 °C, the thermal impedance (Junction to Ambient) θJA = 36.2 °C/W (4-layer PCB) 𝑇𝑗 = 𝑇𝑎𝑚𝑎𝑥 + 𝑃𝐶 × 𝜃𝐽𝐴 = 97.3 °𝐶 When operating the IC, the top center of case’s (mold) temperature TT = 100 °C, ΨJT = 32 °C/W (1-layer PCB) 𝑇𝑗 = 𝑇𝑇 + 𝑃𝐶 × 𝛹𝐽𝑇 = 110.9 °𝐶 If it is difficult to ensure the margin by the calculations above, it is recommended to expand the copper foil area of the board, increasing the layer and thermal via between thermal land pad for optimum thermal performance.

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small -signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Operating Conditions The function and operation of the IC are guaranteed within the range specified by the recommended operating conditions. The characteristic values are guaranteed only under the conditions of each item specified by the electrical characteristics. 6. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 7. Thermal Consideration The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin should be allowed in the thermal design. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation. The amount of heat generat ion depends on the voltage difference between the input and output, load current, and bias current. Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. If Junction temperature is over Tjmax (=150 °C), IC characteristics may be worse due to rising chip temperature. Heat resistance in specification is measurement under PCB condition and environment recommended in JEDEC. Ensure that heat resistance in specification is different from actual environment. 8. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capac itors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 9. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins bein g shorted to each other especially to ground , power supply and output pin . Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. 10. Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charg e it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line.

Regarding the Input Pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. 12. Ceramic Capacitor When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 13. Thermal Shutdown Protection Circuit (TSD) This IC has a built -in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD ci rcuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 14. Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.
