LD2981CU33TR 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.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 1.5V to 5.5V.
  • The maximum output current is 300mA, but it's recommended to keep it below 250mA for optimal performance and to prevent overheating.
  • To reduce noise and ripple, use a low-ESR output capacitor, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground. Also, keep the input voltage as clean as possible.
  • The thermal shutdown temperature is around 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
