LM4040QEEM3-2.5/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a dedicated power plane is also recommended.
  • To ensure stability, use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device, and use a low-ESR capacitor for the output.
  • The maximum allowed input voltage for the LM4040QEEM3-2.5/NOPB is 12V, but it's recommended to keep the input voltage at least 1V above the output voltage to ensure proper regulation.
  • The LM4040QEEM3-2.5/NOPB is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures.
  • The power dissipation of the LM4040QEEM3-2.5/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
