LP2985-28DBVT datasheet by Texas Instruments

LP2985-28DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2985-28DBVT?
  The maximum input voltage that can be applied to the LP2985-28DBVT is 12V, although the recommended operating input voltage range is 5.5V to 10V.
• How do I ensure stability of the output voltage in the LP2985-28DBVT?
  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 output capacitor should be placed as close to the output pin as possible.
• Can I use the LP2985-28DBVT in a high-temperature environment?
  The LP2985-28DBVT is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It is recommended to derate the output current at high temperatures to prevent overheating.
• How do I calculate the power dissipation of the LP2985-28DBVT?
  The power dissipation of the LP2985-28DBVT can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
• Is the LP2985-28DBVT suitable for automotive applications?
  The LP2985-28DBVT is not AEC-Q100 qualified, which is a requirement for many automotive applications. However, it can be used in some automotive applications with proper design and testing to ensure reliability and robustness.
