LP3972SQE-A514/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 1 oz copper thickness is recommended. Refer to the application note SLVAE03 for more details.
  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, add a 10nF capacitor between the VIN pin and GND, and a 1uF capacitor between the VOUT pin and GND. This will help to filter out noise and prevent oscillation.
  • The maximum input voltage that can be applied to the LP3972SQE-A514/NOPB is 15V. Exceeding this voltage may cause damage to the device.
  • The output voltage of the LP3972SQE-A514/NOPB can be adjusted by changing the values of the resistors R1 and R2. Use the formula VOUT = 0.8V x (1 + R2/R1) to calculate the desired output voltage.
  • The minimum input voltage required for the LP3972SQE-A514/NOPB to operate is 2.5V. The device will not operate correctly if the input voltage is below this threshold.
