The maximum input voltage that can be applied to the LT1129IT is 36V, but it's recommended to keep it below 30V for reliable operation.
To ensure stability, make sure to follow the recommended layout and component selection guidelines, and add a 10nF to 100nF capacitor between the VIN and GND pins to filter out high-frequency noise.
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 LT1129IT 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.
