LT1172IS8#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT1172IS8 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a minimum output capacitance of 10uF with an ESR of 1 ohm or less.
-
The LT1172IS8 can deliver up to 3A of output current, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
-
Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LT1172IS8 from input voltage transients and surges.
-
The thermal shutdown temperature of the LT1172IS8 is typically around 150°C, but it can vary depending on the specific device and operating conditions.
