L4938EPD Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L4938EPD is 30V, but it's recommended to keep it below 28V for reliable operation.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and keep the input voltage ripple below 1V.
  • The L4938EPD can operate with a minimum load current of 1mA, but it's recommended to have a load current of at least 10mA for stable operation.
  • The L4938EPD is rated for operation up to 150°C, but its performance may degrade above 125°C. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the L4938EPD from input voltage surges and spikes.
