LD1085V Frequently Asked Questions (FAQ)

  • The LD1085V can handle input voltages up to 30V, but it's recommended to keep it below 25V for optimal performance and reliability.

  • To ensure stability, use a minimum output capacitance of 10uF, and keep the output capacitor's ESR (Equivalent Series Resistance) below 1 ohm. Also, make sure the input capacitor is at least 1uF and has a low ESR.

  • The LD1085V 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 LD1085V 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 reliability.

  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the LD1085V from voltage surges and spikes. This will help prevent damage to the device.
