LM2738XMY/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM2738XMY/NOPB involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces to reduce EMI and noise.
  • To ensure stability, make sure to follow the recommended component values and PCB layout, and add a small capacitor (e.g., 10nF) between the Vout and Vin pins to prevent oscillation.
  • The LM2738XMY/NOPB can handle input voltages up to 42V, but it's recommended to keep the input voltage below 40V to ensure reliable operation.
  • The LM2738XMY/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the LM2738XMY/NOPB can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the internal reference voltage (1.25V).
