LT1112MJ8 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1112MJ8 is 18V, but it's recommended to keep it below 15V for reliable operation.

  • To ensure stability, 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 minimum ESR required for the output capacitor is 0.05 ohms, but it's recommended to use a capacitor with an ESR of 0.01 ohms or less for optimal performance.

  • The LT1112MJ8 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.

  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESR) / (f x C), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and C is the output capacitance.
