LT3971EMSE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT3971EMSE can handle is 40V, but it's recommended to keep it below 36V for reliable operation.
-
To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.
-
The maximum output current that the LT3971EMSE can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation.
-
The output voltage of the LT3971EMSE can be adjusted by using a resistive divider network between the output and the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
-
The EN (enable) pin is used to turn the regulator on or off. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
