LM2585S-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • The LM2585S-5.0/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
  • The LM2585S-5.0/NOPB has a ±2% output voltage tolerance. To ensure an exact 5.0V output, consider using an adjustable voltage regulator like the LM317 or adding a voltage trimming circuit.
  • A minimum of 10uF input capacitance is recommended to ensure stability and prevent oscillations. Use a low-ESR capacitor with a voltage rating of at least 15V.
  • Yes, but be aware that the quiescent current (Iq) is around 5mA, which can affect battery life. Consider using a low-Iq voltage regulator or a power management IC with a lower quiescent current.
