LT3991IMSE#TRPBF Frequently Asked Questions (FAQ)
-
The LT3991 can handle input voltages up to 60V, but it's recommended to keep the input voltage below 50V for optimal performance and reliability.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 0.8V to 15V.
-
The LT3991 can deliver up to 1.5A of output current, but it's recommended to keep the output current below 1.2A for optimal performance and reliability.
-
The output voltage can be adjusted by using a resistive divider network between the output pin and the ground pin. The ratio of the resistors determines the output voltage.
-
The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
