LD1085V18 datasheet by STMicroelectronics

LD1085V18 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1085V18?
  The maximum input voltage that can be applied to the LD1085V18 is 30V, but it's recommended to keep it below 25V for reliable operation.
• How do I ensure the LD1085V18 is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and a minimum input capacitance of 1uF with an ESR of less than 5 ohms.
• What is the minimum load current required for the LD1085V18 to regulate properly?
  The LD1085V18 requires a minimum load current of 5mA to regulate properly. If the load current is less than 5mA, the output voltage may not be regulated accurately.
• Can I use the LD1085V18 in a high-temperature environment?
  The LD1085V18 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.
• How do I protect the LD1085V18 from input voltage surges and spikes?
  To protect the LD1085V18 from input voltage surges and spikes, use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to clamp the input voltage.
