UDZVFHTE-173.9B Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for stable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the input capacitance below 1uF. Also, ensure the PCB layout is designed to minimize noise and parasitic inductance.
  • The dropout voltage is typically around 1.5V, but it can vary depending on the output current and input voltage.
  • The operating temperature range for UDZVFHTE-173.9B is -40°C to 125°C. However, the maximum junction temperature is 150°C, so ensure proper thermal design and heat dissipation to prevent overheating.
  • Calculate the power dissipation using the formula: Pd = (Vin - Vout) x Iout. Ensure the calculated value is within the maximum power dissipation rating of 1.5W.
