LM4819MM/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4819MM 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 input capacitor should be at least 10uF, and the output capacitor should be at least 22uF. The ESR of the capacitors should be low, typically < 0.1 ohms.
  • The LM4819MM is rated for operation from -40°C to 85°C. However, the device may be operated at higher temperatures with derating. Consult the datasheet for thermal derating information.
  • Yes, the LM4819MM is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5mA. However, the device's shutdown feature should be used to minimize power consumption when the device is not in use.
  • To ensure stability, follow the recommended PCB layout, use the recommended input and output capacitors, and ensure that the device is properly decoupled. Additionally, the output voltage should be set to a value that is within the device's specified range.
