LT3991EMSE-3.3#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
-
To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (3.3V ± 2%).
-
The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability and optimal performance.
-
The LT3991EMSE-3.3#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to prevent overheating and ensure reliability.
-
Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and junction temperature to ensure reliable operation.
