LM3478MM Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3478MM?
  The maximum input voltage that can be applied to the LM3478MM is 18V. Exceeding this voltage may damage the device.
• How do I ensure the stability of the output voltage in the LM3478MM?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be placed as close to the output pin as possible.
• What is the maximum output current that the LM3478MM can provide?
  The maximum output current that the LM3478MM can provide is 500mA. Exceeding this current may cause the device to overheat or shut down.
• How do I adjust the output voltage of the LM3478MM?
  The output voltage of the LM3478MM can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage can be calculated using the formula: Vout = 1.24 x (1 + R1/R2).
• What is the purpose of the enable pin on the LM3478MM?
  The enable pin is used to turn the device on or off. When the enable pin is pulled low, the device is in shutdown mode and consumes minimal power. When the enable pin is pulled high, the device is enabled and operates normally.
