LT1963EST-3.3#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1963EST-3.3 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.

  • To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.

  • The minimum input capacitance required for the LT1963EST-3.3 is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) for better performance and noise reduction.

  • The LT1963EST-3.3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's essential to ensure proper thermal management and consider derating the device for high-temperature applications.

  • To reduce noise and ripple, use a low-ESR output capacitor, add a noise-reducing capacitor (e.g., 10nF) between the output and ground, and consider using a noise-filtering component (e.g., ferrite bead) in the output line.
