LM5157RTER Frequently Asked Questions (FAQs)

  • The LM5157RTER can handle input voltages up to 60V, but it's recommended to keep it below 40V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor.
  • The LM5157RTER can provide up to 1.5A of output current, but it's recommended to keep it below 1.2A for optimal performance and reliability.
  • To reduce noise and ripple, use a low-ESR output capacitor, and consider adding a filter capacitor (e.g. 10uF) in parallel with the output capacitor. Also, keep the input and output capacitors close to the device.
  • The thermal shutdown temperature of the LM5157RTER is around 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
