LP2985-33DBVRE4 datasheet by Texas Instruments

LP2985-33DBVRE4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2985-33DBVRE4?
  The maximum input voltage that can be applied to the LP2985-33DBVRE4 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 2.2uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of 0.1 ohm or less.
• What is the minimum input voltage required for the LP2985-33DBVRE4 to operate?
  The minimum input voltage required for the LP2985-33DBVRE4 to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance.
• Can I use the LP2985-33DBVRE4 in a high-temperature environment?
  The LP2985-33DBVRE4 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.
• How do I calculate the output voltage tolerance of the LP2985-33DBVRE4?
  The output voltage tolerance of the LP2985-33DBVRE4 is ±2%. This means that the output voltage can vary by up to 2% of the nominal output voltage of 3.3V, resulting in an output voltage range of 3.234V to 3.366V.
