LM4140BCMX-1.0/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a layout with a solid ground plane, short traces, and minimal inductance to ensure low noise and high accuracy. A 4-layer PCB with a dedicated analog ground plane is recommended.
  • To ensure stability, make sure to follow the recommended capacitor values and placement, and avoid long traces and inductive loops. Additionally, use a low-ESR capacitor for the output capacitor and ensure the input capacitor is properly decoupled.
  • The maximum input voltage is 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation and prevent damage to the device.
  • The LM4140BCMX-1.0/NOPB is rated for operation up to 125°C, but the accuracy and stability may degrade at high temperatures. It's recommended to derate the output voltage and current at high temperatures to ensure reliable operation.
  • The output voltage tolerance is typically ±1% over the operating temperature range. To calculate the output voltage tolerance, use the formula: Output Voltage Tolerance = (Output Voltage x Temperature Coefficient) + (Output Voltage x Line Regulation)
