LM4808MX/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4808MX/NOPB involves keeping the input and output traces short and wide, using a solid ground plane, and placing the decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • The input capacitor should be a low-ESR ceramic capacitor with a value of 2.2uF to 10uF, while the output capacitor should be a low-ESR ceramic or electrolytic capacitor with a value of 10uF to 22uF. The capacitor values and types may vary depending on the specific application and output voltage.
  • The LM4808MX/NOPB can handle input voltages up to 26V, but it's recommended to keep the input voltage below 24V to ensure reliable operation and to prevent damage to the device.
  • The output voltage of the LM4808MX/NOPB can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network. The output voltage can be calculated using the formula: Vout = 1.23V x (1 + R2/R1).
  • The LM4808MX/NOPB can deliver up to 3A of output current, but the maximum output current may be limited by the input voltage, output voltage, and thermal considerations.
