LVR025S Frequently Asked Questions (FAQs)

  • A recommended PCB layout for optimal thermal performance of the LVR025S includes a thermal pad on the bottom of the device, connected to a large copper area on the PCB to dissipate heat efficiently.
  • To ensure proper soldering, use a soldering iron with a temperature of 250°C to 260°C, and apply a small amount of solder paste to the thermal pad. Use a soldering technique that minimizes the time the iron is in contact with the device.
  • The maximum allowed voltage transient for the LVR025S is 40V for a duration of 100ms, as specified in the datasheet. Exceeding this limit may damage the device.
  • The LVR025S is rated for operation up to 150°C, but its performance may degrade at high temperatures. Ensure that the device is properly heat-sinked and that the operating temperature is within the specified range.
  • To calculate the power dissipation of the LVR025S, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
