LM3478QMMX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3478QMMX/NOPB is 18V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
  • The maximum output current that the LM3478QMMX/NOPB can provide is 500mA. Exceeding this current may cause the device to overheat or malfunction.
  • To reduce the noise and ripple in the output voltage, it is recommended to add a 10uF capacitor between the VOUT and GND pins, and a 100nF capacitor between the VIN and GND pins. Additionally, using a low-ESR output capacitor can also help to reduce the noise and ripple.
  • The thermal shutdown temperature of the LM3478QMMX/NOPB is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
