LP2985-18DBVT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP2985-18DBVT 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 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 10uF with an ESR of 0.1 ohm or less.
  • The minimum input voltage required for the LP2985-18DBVT to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance.
  • The LP2985-18DBVT 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 LP2985-18DBVT can be calculated using the following formula: Vout = 1.8V * (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
