LT1185IQ#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT1185IQ#PBF 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, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
-
The minimum input voltage required for the LT1185IQ#PBF to operate is 3.5V, but it's recommended to keep it above 4V for optimal performance.
-
The LT1185IQ#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliability and prevent overheating.
-
To reduce the noise and ripple in the output voltage, use a low-ESR output capacitor, add a noise-reducing capacitor (e.g. 10nF) between the output and ground, and ensure good PCB layout and grounding practices.
