REF198FSZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the REF198FSZ involves keeping the device away from high-current carrying traces, using a solid ground plane, and minimizing the distance between the device and the decoupling capacitors. Additionally, it's recommended to use a star-ground configuration and to avoid routing digital signals near the device.
  • To ensure proper decoupling, use a 10uF ceramic capacitor with a low ESR (Equivalent Series Resistance) between the VOUT pin and the GND pin, and place it as close to the device as possible. Additionally, use a 1uF ceramic capacitor between the VIN pin and the GND pin to filter the input voltage.
  • The maximum allowed voltage drop between the input and output of the REF198FSZ is 200mV. Exceeding this voltage drop may affect the device's accuracy and stability.
  • To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and avoid mounting the device near heat sources. The REF198FSZ has a thermal shutdown feature that activates when the junction temperature exceeds 150°C, but it's still important to follow proper thermal design practices.
  • The recommended input voltage range for the REF198FSZ is 4.5V to 18V. The output voltage remains stable and regulated as long as the input voltage is within this range. However, if the input voltage drops below 4.5V, the output voltage may not be regulated, and if it exceeds 18V, the device may be damaged.
