LDI1117-1.8U Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LDI1117-1.8U is 15V, although it's recommended to keep it below 12V for optimal performance and reliability.
-
The LDI1117-1.8U is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliability and prevent thermal shutdown.
-
To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and keep the input capacitance as low as possible. Also, avoid using long, thin traces for the output voltage line.
-
The LDI1117-1.8U has a relatively high dropout voltage of around 1.5V, so it's not suitable for low-dropout applications. If you need a low-dropout regulator, consider using a different part with a lower dropout voltage.
-
To protect the LDI1117-1.8U from input voltage transients, consider adding a TVS diode or a transient voltage suppressor at the input. This will help absorb voltage spikes and prevent damage to the regulator.
