LT1084MK-5 datasheet by Linear Technology

LT1084MK-5 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that I can apply to the LT1084MK-5?
  The maximum input voltage for the LT1084MK-5 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• Can I use the LT1084MK-5 in a high-current application?
  The LT1084MK-5 is rated for up to 5A of output current, but it's essential to ensure proper heat sinking and thermal management to prevent overheating. A heat sink with a thermal resistance of less than 10°C/W is recommended.
• How do I choose the correct output capacitor for the LT1084MK-5?
  The output capacitor should have a minimum value of 10uF and an ESR (Equivalent Series Resistance) of less than 1 ohm. A low-ESR capacitor such as a ceramic or tantalum capacitor is recommended to ensure stability and prevent oscillations.
• Can I use the LT1084MK-5 in a switching regulator application?
  No, the LT1084MK-5 is a linear voltage regulator and is not designed for use in switching regulator applications. It's intended for use in linear power supply applications where a fixed output voltage is required.
• How do I protect the LT1084MK-5 from input voltage transients?
  To protect the LT1084MK-5 from input voltage transients, it's recommended to add a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input. This will help prevent damage to the regulator from voltage spikes or surges.
