LD1085D2M33R Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LD1085D2M33R 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 minimum capacitance of 10uF and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.

  • The LD1085D2M33R 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 LD1085D2M33R 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 LD1085D2M33R from input voltage surges, it's recommended to use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor. This will help to clamp the input voltage and prevent damage to the device.
