LTM2881MPY-5#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTM2881 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the LTM2881 and the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • To ensure proper powering and decoupling of the LTM2881, use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) between the VIN pin and the GND pin, and a 0.1uF ceramic capacitor between the VCC pin and the GND pin. Additionally, use a 1uF capacitor between the VOUT pin and the GND pin.
  • The maximum cable length for the USB interface of the LTM2881 is 3 meters (10 feet) for a standard USB cable. However, this can be extended up to 5 meters (16.4 feet) using an active USB repeater or a high-quality, shielded USB cable.
  • To configure the LTM2881 for a specific voltage output, use the VOUT pin and the RES pin to set the output voltage. The VOUT pin sets the output voltage range, and the RES pin sets the output voltage precision. Consult the datasheet for specific resistor values and voltage output ranges.
  • The thermal derating of the LTM2881 is 1.5°C/W (junction-to-ambient thermal resistance). This means that for every 1°C increase in ambient temperature, the maximum power dissipation of the LTM2881 decreases by 1.5°C.
