LT1172CQ#PBF Frequently Asked Questions (FAQ)
-
The LT1172CQ can handle input voltages up to 60V, but it's recommended to keep the input voltage below 40V 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, use a low-ESR capacitor for the output filter capacitor.
-
The LT1172CQ can provide up to 3A of output current, but it's recommended to keep the output current below 2.5A for optimal performance and reliability.
-
The output voltage can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage is determined by the ratio of the resistors in the divider network.
-
The adjust pin is used to adjust the output voltage of the regulator. It's connected to a resistive divider network that sets the output voltage. It's also used to monitor the output voltage and provide feedback to the regulator.
