LM1085IT-5.0/NOPB datasheet by Texas Instruments

LM1085IT-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM1085IT-5.0/NOPB can handle?
  The maximum input voltage is 25V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.5 ohms or less, and a minimum input capacitance of 1uF with an ESR of 1 ohm or less.
• What is the dropout voltage of the LM1085IT-5.0/NOPB?
  The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
• Can I use the LM1085IT-5.0/NOPB in a high-temperature environment?
  The LM1085IT-5.0/NOPB is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.
• How do I calculate the power dissipation of the LM1085IT-5.0/NOPB?
  Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
