TPS72301DBVT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TPS72301DBVT to minimize noise and ensure stability?
  A good PCB layout for the TPS72301DBVT involves placing the input and output capacitors close to the device, using a solid ground plane, and keeping the feedback network as short as possible. Additionally, it's recommended to use a separate analog ground plane and to avoid routing digital signals near the device.
• How do I ensure the TPS72301DBVT is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout, use the correct output capacitor value and type, and add a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability. Also, avoid using long feedback traces and keep the feedback network as short as possible.
• What is the maximum input voltage that the TPS72301DBVT can handle?
  The TPS72301DBVT can handle input voltages up to 15V, but it's recommended to keep the input voltage below 12V to ensure reliable operation and to prevent overheating.
• Can I use the TPS72301DBVT in a high-temperature environment?
  The TPS72301DBVT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
• How do I calculate the output voltage of the TPS72301DBVT?
  The output voltage of the TPS72301DBVT can be calculated using the formula: Vout = 1.22 x (1 + R1/R2), where R1 and R2 are the feedback resistors. Make sure to choose the correct resistor values to achieve the desired output voltage.
