LT1185CQ#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT1185CQ can handle is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
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, keep the output voltage within the recommended range of 2.5V to 9.5V.
-
The maximum output current that the LT1185CQ can provide is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
-
To reduce the noise and ripple on the output voltage, use a low-ESR output capacitor, and add a 10nF to 100nF ceramic capacitor in parallel with the output capacitor. Also, keep the input voltage as clean as possible.
-
The thermal shutdown temperature of the LT1185CQ is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 140°C.
