LT1990CS8#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT1990CS8 involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing the input and output capacitors close to the device. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range, and the output voltage is set correctly using the feedback resistors.
  • The maximum power dissipation of the LT1990CS8 is dependent on the package type and the ambient temperature. For the CS8 package, the maximum power dissipation is 1.4W at 25°C ambient temperature.
  • Yes, the LT1990CS8 can be used as a current source. To do so, connect the output to a current sense resistor, and use the feedback pin to regulate the current. However, note that the device is not designed for high-current applications, and the maximum output current is limited to 200mA.
  • To protect the LT1990CS8 from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. This will help to limit the voltage at the input pin and prevent damage to the device.
