LD1085CDT-R Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LD1085CDT-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, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the regulator to minimize noise and oscillations.

  • The minimum input voltage required for the LD1085CDT-R to function properly is 7V, but it's recommended to keep it above 8V for optimal performance and stability.

  • The LD1085CDT-R is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent overheating.

  • To protect the LD1085CDT-R from input voltage transients and spikes, use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to clamp the voltage and prevent damage to the regulator.
