LMX2470SLEX/NOPB datasheet by Texas Instruments

LMX2470SLEX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the LMX2470SLEX/NOPB?
  A good PCB layout for the LMX2470SLEX/NOPB involves keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated ground plane is recommended.
• How do I ensure the LMX2470SLEX/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Also, ensure that the output capacitor is properly sized and placed close to the device. Additionally, a series resistor can be added to the output to improve stability.
• What is the maximum input voltage that the LMX2470SLEX/NOPB can handle?
  The maximum input voltage that the LMX2470SLEX/NOPB can handle is 6.5V. Exceeding this voltage may damage the device.
• How do I calculate the output voltage of the LMX2470SLEX/NOPB?
  The output voltage of the LMX2470SLEX/NOPB can be calculated using the formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the feedback resistors, Vin is the input voltage, and Vref is the reference voltage.
• What is the thermal shutdown temperature of the LMX2470SLEX/NOPB?
  The thermal shutdown temperature of the LMX2470SLEX/NOPB is typically around 150°C. The device will shut down when the junction temperature exceeds this value.
