LT1959IS8#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT1959IS8#PBF can handle is 36V, but it's recommended to operate it within the specified input voltage range of 3.5V to 36V for optimal performance and reliability.
-
To ensure the stability of the output voltage, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a sufficient output capacitor with a low ESR (Equivalent Series Resistance) to minimize output voltage ripple and oscillation.
-
The minimum input capacitance required for the LT1959IS8#PBF is 10uF, but it's recommended to use a higher value (e.g., 22uF) to ensure stable operation and minimize input voltage ripple.
-
The LT1959IS8#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation and prevent overheating.
-
The output voltage of the LT1959IS8#PBF can be calculated using the formula: Vout = 0.8V * (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
