LT1121CST-3.3#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
-
To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, keep the input voltage ripple low and use a clean and stable input voltage source.
-
The minimum input voltage required is 3.5V, but it's recommended to keep it above 4V for optimal performance and to ensure the output voltage remains stable.
-
The LT1121CST-3.3#PBF is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability. Make sure to provide adequate heat sinking and thermal management.
-
The output voltage tolerance is typically ±2% over the entire operating temperature range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (3.3V) by the tolerance percentage (2%).
