LT3518EFE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3518EFE#PBF can handle?
  The maximum input voltage that the LT3518EFE#PBF can handle is 36V, but it's recommended to keep it below 30V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in the LT3518EFE#PBF?
  To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
• What is the maximum output current that the LT3518EFE#PBF can provide?
  The maximum output current that the LT3518EFE#PBF can provide is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.
• How do I reduce the noise and ripple in the output voltage of the LT3518EFE#PBF?
  To reduce the noise and ripple in the output voltage, use a low-ESR output capacitor, and consider adding a noise-reducing capacitor (e.g. 10nF) between the VOUT and GND pins. Also, ensure that the input voltage is well-filtered and the PCB layout is optimized for low noise.
• What is the thermal shutdown temperature of the LT3518EFE#PBF?
  The thermal shutdown temperature of the LT3518EFE#PBF is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 140°C.
