LM2574M-ADJ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2574M-ADJ is 40V. Exceeding this voltage can cause damage to the device.
  • The output voltage of the LM2574M-ADJ can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
  • The minimum input voltage required for the LM2574M-ADJ to operate is 3V. However, the device can operate down to 2.5V with reduced performance.
  • The LM2574M-ADJ 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 device's output current and voltage at high temperatures.
  • To ensure the stability of the LM2574M-ADJ output voltage, it's recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 10uF with a low ESR.
