LM4819MX/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4819MX 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.
  • Choose X7R or X5R ceramic capacitors with a voltage rating of at least 2x the maximum input voltage. The capacitance value should be at least 2.2uF for the input capacitor and 4.7uF for the output capacitor. Ensure the capacitors are placed close to the device and have a low ESR.
  • The LM4819MX can operate in an ambient temperature range of -40°C to 85°C. However, the device's junction temperature should not exceed 150°C.
  • Yes, the LM4819MX is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5mA. However, ensure that the device is properly shut down when not in use to minimize power consumption.
  • To ensure stability, ensure that the output capacitor has a low ESR, the input capacitor is properly sized, and the device is properly decoupled. Also, avoid using a capacitor with a high ESL (Equivalent Series Inductance) in the output filter.
