LT1117CST-5 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT1117CST-5 is 15V, but it's recommended to keep it below 12V for reliable operation.
-
The LT1117CST-5 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures.
-
To ensure stability, use a minimum output capacitance of 10uF with an ESR of less than 1 ohm, and keep the input capacitance to a minimum. Also, avoid using ceramic capacitors with high ESL.
-
The LT1117CST-5 has a dropout voltage of around 1.2V, so it's not suitable for low-dropout applications. Consider using a low-dropout regulator like the LT1965 instead.
-
Use a TVS diode or a transient voltage suppressor at the input to protect the LT1117CST-5 from voltage transients. Also, consider adding a series resistor and capacitor to filter out high-frequency noise.
