LT1963AEQ-3.3 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1963AEQ-3.3 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.

  • To ensure the stability of the output voltage, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.

  • The LT1963AEQ-3.3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curves in the datasheet.

  • The power dissipation of the LT1963AEQ-3.3 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. Make sure to consider the thermal resistance of the package and the PCB layout when calculating the junction temperature.

  • The LT1963AEQ-3.3 has a relatively high noise figure, so it may not be suitable for powering noise-sensitive circuits. Consider using a low-noise LDO regulator or adding additional filtering components to reduce the output noise.
