LT1790BCS6-2.5#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT1790 involves keeping the input and output traces short and separate, using a solid ground plane, and placing the 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 keep the input and output resistors within the recommended range. Also, avoid using long input traces and ensure that the device is properly bypassed.
  • The maximum power dissipation of the LT1790 is dependent on the package and the ambient temperature. For the S6 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 LT1790 can be used as a voltage regulator, it is not recommended due to its limited output current capability and lack of short-circuit protection. The LT1790 is primarily designed as a voltage reference, and it is recommended to use a dedicated voltage regulator IC for voltage regulation applications.
  • The output voltage tolerance of the LT1790 can be calculated by adding the initial accuracy, temperature coefficient, and output voltage noise. The datasheet provides the specifications for each of these parameters, and the total output voltage tolerance can be calculated using the root sum square method.
