LP38690DT-3.3 Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
  • To ensure stability, use a minimum output capacitor of 10uF, and ensure that the output capacitor's ESR (Equivalent Series Resistance) is less than 1 ohm.
  • The maximum input voltage that the LP38690DT-3.3 can handle is 15V, but it's recommended to keep the input voltage below 12V for optimal performance.
  • The LP38690DT-3.3 is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to ensure reliability.
  • The power dissipation of the LP38690DT-3.3 can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
