LT1795IFE#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT1795 involves keeping the input and output traces short and separate, using a solid ground plane, and placing the input and output 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 component values and PCB layout guidelines. Also, ensure that the output capacitor is properly sized and placed, and that the input and output traces are not too long or too close to each other. Additionally, consider adding a small series resistor (e.g. 1-10 ohms) at the output to dampen any oscillations.
  • The maximum input voltage that the LT1795 can handle is 15V, but it's recommended to keep the input voltage below 12V to ensure reliable operation and to prevent damage to the device.
  • While the LT1795 can be used as a voltage regulator, it's not the most suitable device for this application. The LT1795 is primarily designed as a voltage reference, and its output current capability is limited to 10mA. If you need a voltage regulator, consider using a dedicated voltage regulator IC like the LT1085 or LT1965.
  • The voltage reference output of the LT1795 is accurate to within ±0.5% over the entire operating temperature range of -40°C to 125°C. However, this accuracy can be affected by factors such as input voltage, output current, and PCB layout.
