LP2981A-33DBVR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP2981A-33DBVR is 12V. Exceeding this voltage may damage the device.
  • To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 2.2uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of 1 ohm or less.
  • The minimum input voltage required for the LP2981A-33DBVR to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance.
  • The LP2981A-33DBVR is rated for operation up to 125°C. However, the device's performance may degrade at high temperatures, and the output voltage may drop. It is recommended to derate the output current at high temperatures.
  • The output voltage of the LP2981A-33DBVR is fixed at 3.3V and is not adjustable. The device is designed to provide a regulated 3.3V output voltage with a tolerance of ±2%.
