LM25145RGYT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM25145RGYT is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, it's essential to use the recommended output capacitor value and type, and to follow the layout guidelines provided in the datasheet.
  • The minimum input capacitance required is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better performance and stability.
  • Yes, the LM25145RGYT is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain reliable operation.
  • The output voltage can be calculated using the formula: Vout = (R1 / R2) * (1.22V), where R1 and R2 are the resistors in the feedback network.
