LM4140ACM-1.0/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4140ACM-1.0/NOPB involves keeping the input and output traces short and separate, 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.
  • To ensure stability, make sure to follow the recommended PCB layout, use a minimum output capacitance of 10uF, and add a 1uF decoupling capacitor between the VIN and GND pins. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limit.
  • The maximum input voltage that can be applied to the LM4140ACM-1.0/NOPB is 5.5V. Exceeding this voltage may damage the device.
  • The LM4140ACM-1.0/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
  • The output voltage of the LM4140ACM-1.0/NOPB is fixed at 1.0V. The device is a voltage reference, and the output voltage is internally regulated to 1.0V ± 1%.
