LM1085IT-ADJ datasheet by Texas Instruments

LM1085IT-ADJ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM1085IT-ADJ?
  The maximum input voltage is 25V, but it's recommended to keep it below 20V for reliable operation.
• How do I adjust the output voltage of the LM1085IT-ADJ?
  The output voltage can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
• What is the minimum input voltage required for the LM1085IT-ADJ to operate?
  The minimum input voltage is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM1085IT-ADJ in a high-temperature environment?
  The LM1085IT-ADJ is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating.
• How do I protect the LM1085IT-ADJ from input voltage transients?
  A capacitor (e.g., 10uF) can be connected between the input and ground to filter out voltage transients. Additionally, a voltage clamp (e.g., a zener diode) can be used to protect the regulator from high-voltage spikes.
