LM1085ISX-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.

  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 1 ohm.

  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for optimal performance and to prevent overheating.

  • To prevent overheating, ensure good airflow around the device, use a heat sink if necessary, and keep the input voltage and output current within the recommended ranges.

  • The LM1085ISX-3.3/NOPB is rated for operation up to 125°C, but the output current and input voltage should be derated at higher temperatures to prevent overheating.
