LT1720CDD#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT1720 involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing bypass capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
  • To ensure stability, make sure to follow the recommended compensation network, use a minimum output capacitance of 10uF, and avoid capacitive loads. Also, ensure that the input voltage is within the recommended range and the device is operated within its specified temperature range.
  • The maximum power dissipation of the LT1720 is dependent on the package type and the ambient temperature. For the DDD package, the maximum power dissipation is 1.4W at 25°C ambient temperature. However, it is recommended to derate the power dissipation based on the ambient temperature and the thermal resistance of the package.
  • While the LT1720 is a voltage reference, it can be used as a voltage regulator with some additional components. However, it is not recommended as it is not designed to handle high currents and may not provide the necessary regulation accuracy. Instead, consider using a dedicated voltage regulator IC.
  • The output voltage tolerance of the LT1720 is specified as ±0.5% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage. For example, for a 2.5V output, the tolerance would be ±12.5mV.
