LP2985A-18DBVT datasheet by Texas Instruments

LP2985A-18DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2985A-18DBVT?
  The maximum input voltage that can be applied to the LP2985A-18DBVT is 12V. Exceeding this voltage may damage the device.
• How do I ensure stability of the output voltage?
  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 output capacitor should be placed as close to the output pin as possible.
• What is the minimum input capacitance required for the LP2985A-18DBVT?
  The minimum input capacitance required for the LP2985A-18DBVT is 1uF. However, it is recommended to use a higher value capacitor, such as 4.7uF, to ensure stability and reduce noise.
• Can I use the LP2985A-18DBVT in a high-temperature environment?
  The LP2985A-18DBVT 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 at high temperatures.
• How do I calculate the power dissipation of the LP2985A-18DBVT?
  The power dissipation of the LP2985A-18DBVT can be calculated using the formula: Pd = (Vin - Vout) x Iout. Where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
