LMR1802G-LBTR Frequently Asked Questions (FAQs)

  • A good PCB layout for optimal thermal performance would be to have a solid ground plane on the bottom layer, and to use thermal vias to connect the exposed pad to the ground plane. This helps to dissipate heat efficiently.
  • To ensure the stability of the output voltage, it's recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. Additionally, the output capacitor should be placed as close to the output pin as possible to minimize the loop inductance.
  • Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and to prevent damage to the device.
  • While the LMR1802G-LBTR is rated for operation up to 125°C, it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation and to prevent thermal runaway.
  • The power dissipation of the LMR1802G-LBTR 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.
