LP2985IM5-2.5/NOPB datasheet by Texas Instruments

LP2985IM5-2.5/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2985IM5-2.5/NOPB?
  The maximum input voltage that can be applied to the LP2985IM5-2.5/NOPB is 12V. Exceeding this voltage may damage the device.
• How do I ensure stability of the output voltage in my design?
  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 LP2985IM5-2.5/NOPB to operate?
  The minimum input voltage required for the LP2985IM5-2.5/NOPB to operate is 2.7V. The device will not regulate the output voltage if the input voltage is below this threshold.
• Can I use the LP2985IM5-2.5/NOPB in a high-temperature environment?
  The LP2985IM5-2.5/NOPB 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 to ensure reliable operation in high-temperature environments.
• How do I calculate the power dissipation of the LP2985IM5-2.5/NOPB?
  The power dissipation of the LP2985IM5-2.5/NOPB 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.
