LP2981-28DBVR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP2981-28DBVR is 12V, although the recommended operating input voltage range is 5.5V to 10V.
  • To ensure stability of the output voltage, a minimum output capacitance of 2.2uF is recommended, and the output capacitor should be placed as close to the output pin as possible.
  • The LP2981-28DBVR is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Thermal derating is required for operation above 85°C.
  • The power dissipation of the LP2981-28DBVR 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.
  • The LP2981-28DBVR is not AEC-Q100 qualified, which is a requirement for many automotive applications. However, it can be used in some automotive applications with proper validation and testing.
