LD1085D2T-R Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LD1085D2T-R is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Additionally, the input capacitor should be at least 1uF with a low ESR.
-
The LD1085D2T-R requires a minimum load current of 5mA to maintain regulation. If the load current is less than 5mA, the output voltage may not be regulated properly.
-
The LD1085D2T-R 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 according to the temperature derating curve in the datasheet.
-
To protect the LD1085D2T-R from input voltage surges and spikes, it's recommended to use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor.
