LM1771SSD/NOPB Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM1771SSD/NOPB is 1.4W, but it can be increased to 2.5W with proper heat sinking.
  • No, the LM1771SSD/NOPB is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage.
  • The LM1771SSD/NOPB has an operating temperature range of -40°C to 125°C, but the accuracy of the voltage reference is specified over a range of -20°C to 85°C.
  • Yes, the LM1771SSD/NOPB is a high-reliability device, with a failure rate of less than 100 FIT (failures per 10^9 hours) at 125°C. It is suitable for use in high-reliability applications such as aerospace, automotive, and medical devices.
  • To minimize noise and ensure accurate voltage reference, it is recommended to follow good PCB layout practices, such as keeping the input and output pins separate, using a ground plane, and minimizing the distance between the device and the bypass capacitors.
