LM2596T-ADJ/LF02 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The output voltage can be set by connecting a resistor divider network between the output and the ADJ pin. The formula to calculate the output voltage is Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • The minimum input voltage required is 4V, but it's recommended to keep it above 5V for reliable operation.
  • The LM2596T-ADJ/LF02 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • To ensure stability, it's recommended to use a minimum output capacitance of 22uF, and to keep the output voltage within the recommended range of 1.23V to 37V.
