LP2989AIMM-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP2989 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
  • To ensure stability of the output voltage, it's essential 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 1 ohm or less.
  • The minimum input voltage required for the LP2989 to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance.
  • The LP2989 is rated for operation up to 125°C, but it's essential to ensure proper thermal management and heat sinking to prevent overheating. A thermal pad is recommended to improve heat dissipation.
  • To reduce noise and ripple on the output voltage, use a larger output capacitor (up to 10uF) and add a 10nF capacitor in parallel with the output capacitor. Additionally, ensure that the input capacitor is properly decoupled.
