LP2951DR Frequently Asked Questions (FAQs)

  • The LP2951DR can handle input voltages up to 30V, but it's recommended to keep the input voltage at least 2V above the output voltage to ensure proper regulation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.05 ohms or less, and a minimum input capacitance of 1uF with an ESR of 0.1 ohms or less.
  • The LP2951DR can provide up to 50mA of output current, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
  • The output voltage of the LP2951DR can be adjusted by connecting a resistor divider network between the output and the adjust pin, and then connecting the adjust pin to the input voltage through a resistor.
  • The quiescent current of the LP2951DR is typically around 50uA, but it can vary depending on the input voltage and output current.
