XTR108EA/2K5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout for the XTR108EA/2K5 involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the power source. TI provides a recommended layout in the datasheet and application notes.
• How do I ensure accurate voltage regulation with this device?
  To ensure accurate voltage regulation, it's essential to follow the recommended input and output capacitor values, and to use a stable input voltage source. Additionally, the device's output voltage can be adjusted using the ADJ pin, and the output voltage tolerance can be improved by using a voltage reference IC.
• What are the thermal considerations for this device?
  The XTR108EA/2K5 has a thermal shutdown feature that activates when the junction temperature exceeds 150°C. To prevent overheating, ensure good airflow, use a heat sink if necessary, and follow the recommended PCB layout to minimize thermal resistance.
• How do I protect the device from input voltage transients?
  To protect the XTR108EA/2K5 from input voltage transients, use a TVS (transient voltage suppressor) diode or a voltage clamp circuit at the input. This will help prevent damage from voltage spikes or surges.
• What are the EMI considerations for this device?
  To minimize EMI, use a shielded enclosure, keep the input and output cables short, and use a common-mode choke or ferrite bead on the input and output lines. Additionally, follow good PCB layout practices, such as separating analog and digital grounds.
