LP2985-33DBVR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP2985-33DBVR 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 0.1 ohm.
  • The minimum input voltage required for the LP2985-33DBVR to operate is 3.5V. The device will not regulate the output voltage if the input voltage is below this threshold.
  • The LP2985-33DBVR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and input voltage to ensure reliable operation.
  • The output voltage tolerance of the LP2985-33DBVR is ±2%. This means that the output voltage can vary by up to 2% of the nominal output voltage (3.3V) due to manufacturing tolerances and operating conditions.
