RT9187GQV Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure that the thermal pad is connected to a large copper area to dissipate heat efficiently.
  • Choose an output capacitor with low ESR (Equivalent Series Resistance) and high ripple current rating. A 22μF to 47μF ceramic capacitor with X5R or X7R dielectric is recommended.
  • A 10μF to 22μF ceramic capacitor with X5R or X7R dielectric is recommended for the input capacitor. Ensure that the capacitor is rated for the input voltage and has low ESR.
  • Ensure that the input voltage is within the recommended range (4.5V to 18V), and the output voltage is set within the specified range (0.8V to 3.3V). Also, ensure that the junction temperature is within the recommended range (-40°C to 125°C).
  • Keep the feedback network as short as possible, and use a separate analog ground plane to minimize noise coupling. Ensure that the feedback resistors are placed close to the IC and use a low-noise, low-ESR capacitor for the feedback capacitor.
