LP3988QMFX-2P85 Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor can help to reduce input voltage ripple and improve output voltage regulation.
  • To ensure stability, it is recommended to use a minimum output capacitor of 2.2uF with an ESR (Equivalent Series Resistance) of 0.1 ohms or less. Additionally, the output capacitor should be placed as close as possible to the output pin of the regulator.
  • The maximum dropout voltage for LP3988QMFX-2P85 is 1.2V. This means that the input voltage should be at least 1.2V higher than the output voltage to ensure proper regulation.
  • Yes, LP3988QMFX-2P85 is rated for operation up to 125°C. However, the maximum junction temperature should not exceed 150°C. It is recommended to derate the output current and input voltage according to the thermal derating curve provided in the datasheet.
  • The power dissipation of LP3988QMFX-2P85 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. The maximum power dissipation should not exceed 1.5W.
