LT3080EDD-1 datasheet by Linear Technology

LT3080EDD-1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT3080EDD-1?
  The maximum input voltage that can be applied to the LT3080EDD-1 is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure stability in the LT3080EDD-1 output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage sense lines short and away from noise sources.
• Can I use the LT3080EDD-1 in a high-temperature environment?
  The LT3080EDD-1 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and voltage according to the datasheet's thermal derating curves.
• How do I protect the LT3080EDD-1 from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LT3080EDD-1 from input voltage transients. Also, make sure to follow proper PCB layout and routing guidelines to minimize noise and ringing.
• Can I use the LT3080EDD-1 in a low-dropout application?
  The LT3080EDD-1 is not a low-dropout regulator, and it requires a minimum input-to-output voltage differential of 1.5V to maintain regulation. If you need a low-dropout regulator, consider using a different part, such as the LT3015.
