LP38690DT-1.8/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LP38690DT-1.8/NOPB involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce noise and EMI.
  • To ensure stability, ensure that the output capacitor is properly sized, the input voltage is within the recommended range, and the device is operated within its specified temperature range. Additionally, adding a small capacitor (e.g., 10nF) between the output and ground can help prevent oscillations.
  • While the datasheet specifies a maximum input voltage of 15V, it's recommended to limit the input voltage to 12V to ensure reliable operation and prevent damage to the device.
  • While the device is rated for operation up to 125°C, it's essential to consider the derating curves and thermal management in high-temperature applications to ensure reliable operation and prevent overheating.
  • The output voltage ripple and noise can be calculated using the equations provided in the datasheet, taking into account the input voltage, output voltage, and output current. Additionally, using a larger output capacitor and adding a noise-reducing capacitor (e.g., 10uF) between the output and ground can help minimize ripple and noise.
