LP3907QTL-VXSS/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the device to improve thermal performance. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • To ensure reliable operation in high-temperature environments, it is recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet. Additionally, ensure good airflow and thermal conduction to the PCB.
  • Texas Instruments recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for optimal performance. The capacitor should be placed as close as possible to the VIN pin to minimize noise and ripple.
  • To troubleshoot output voltage instability or oscillation issues, check the PCB layout for any signs of noise or ringing, ensure that the input capacitor is properly sized and placed, and verify that the output capacitor is properly sized and has a low ESR. Also, check for any signs of overheating or thermal issues.
  • Texas Instruments recommends using a low-ESR ceramic capacitor with a value of 10uF to 47uF for optimal performance. The capacitor should be placed as close as possible to the VOUT pin to minimize noise and ripple.
