LMS8117AMP-1.8/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LMS8117AMP-1.8/NOPB should include a solid ground plane, a separate power plane for the input voltage, and a thermal relief pattern on the exposed pad to ensure good heat dissipation. TI provides a recommended PCB layout in the datasheet.
  • To ensure stability in the output voltage, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, the output capacitor should be chosen carefully, taking into account the equivalent series resistance (ESR) and the output voltage ripple requirements.
  • Although 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 ceramic capacitors can be used, they may not be the best choice due to their high ESR. A low-ESR capacitor, such as an electrolytic or tantalum capacitor, is recommended to ensure stability and minimize output voltage ripple.
  • The power dissipation of the LMS8117AMP-1.8/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout. It's essential to consider the thermal resistance of the package and the PCB layout to ensure the device operates within the recommended temperature range.
