LP2985A-28DBVR datasheet by Texas Instruments

LP2985A-28DBVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2985A-28DBVR?
  The maximum input voltage that can be applied to the LP2985A-28DBVR is 12V, although it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the LP2985A-28DBVR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 2.2uF), and keep the input and output capacitors close to the device.
• Can I use the LP2985A-28DBVR in a high-temperature environment?
  The LP2985A-28DBVR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper thermal management to prevent overheating.
• How do I calculate the output voltage tolerance of the LP2985A-28DBVR?
  The output voltage tolerance of the LP2985A-28DBVR is typically ±2% over the entire operating range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (2.8V) by the tolerance percentage (±2%).
• Is the LP2985A-28DBVR suitable for powering noise-sensitive analog circuits?
  The LP2985A-28DBVR is a low-noise LDO regulator, but it's not suitable for powering extremely noise-sensitive analog circuits. For such applications, consider using a more specialized low-noise LDO regulator or adding additional filtering components.
