LD1085V18 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LD1085V18 is 30V, but it's recommended to keep it below 25V for reliable operation.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and a minimum input capacitance of 1uF with an ESR of less than 5 ohms.
-
The LD1085V18 requires a minimum load current of 5mA to regulate properly. If the load current is less than 5mA, the output voltage may not be regulated accurately.
-
The LD1085V18 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 input voltage at high temperatures to ensure reliable operation.
-
To protect the LD1085V18 from input voltage surges and spikes, use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to clamp the input voltage.
