LM78S40CN/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 35V, but it's recommended to keep it below 25V for reliable operation.
  • The LM78S40CN/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.
  • Use a minimum of 10uF capacitor on the input and output pins, and ensure the input voltage is at least 2V above the desired output voltage. Also, keep the regulator away from noise sources and ensure good PCB layout practices.
  • No, the LM78S40CN/NOPB is a linear regulator, not suitable for switching power supply applications. It's designed for low-dropout, low-noise, and high-reliability applications.
  • The LM78S40CN/NOPB can regulate with no minimum load current, but it's recommended to have at least 5mA load current for optimal performance.
