The maximum input voltage that can be applied to the LT1963AEQ-1.8 is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal circuitry.
To ensure the stability of the output voltage, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Additionally, avoid using long traces and minimize the distance between the input and output pins.
The minimum input voltage required for the LT1963AEQ-1.8 to operate is 2.5V, but it's recommended to keep it above 2.7V to ensure reliable startup and operation.
The LT1963AEQ-1.8 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation. Consult the datasheet for more information on thermal derating.
The output voltage ripple of the LT1963AEQ-1.8 can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. Consult the datasheet for more information on output voltage ripple and how to minimize it.
