TPS1100DR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TPS1100DR?
  A good PCB layout for the TPS1100DR involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the stability of the TPS1100DR in my design?
  To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, the output capacitor should be selected based on the specific application requirements, and the input capacitor should be chosen to ensure a stable input voltage.
• What is the maximum input voltage that the TPS1100DR can handle?
  The TPS1100DR can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range of 2.7V to 15V for optimal performance and reliability.
• Can I use the TPS1100DR in a high-temperature environment?
  The TPS1100DR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and heat dissipation in the system to ensure reliable operation.
• How do I calculate the output voltage of the TPS1100DR?
  The output voltage of the TPS1100DR can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage, and R1 and R2 are the resistors in the feedback network.
