The maximum input voltage that can be applied to the LT3020EDD is 36V, but it's recommended to operate within the specified input voltage range of 3.5V to 30V for optimal performance and reliability.
To ensure stability in the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor. Additionally, the input voltage should be well-regulated and free of noise.
The LT3020EDD is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage according to the temperature derating curves provided in the datasheet.
The output voltage of the LT3020EDD can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage can be adjusted from 0.8V to 15V using this formula.
The typical dropout voltage of the LT3020EDD is around 300mV at an output current of 1A, but it can vary depending on the input voltage, output current, and temperature. The dropout voltage is typically specified as the difference between the input voltage and the output voltage when the device is in dropout mode.
