LT317AHVH datasheet by Linear Technology

LT317AHVH Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT317AHVH?
  The maximum input voltage that can be applied to the LT317AHVH is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure stability when using the LT317AHVH?
  To ensure stability, use a minimum output capacitance of 10uF, and a minimum ESR of 0.05 ohms. Also, make sure the input capacitor is at least 1uF and is placed close to the input pin.
• What is the minimum load current required for the LT317AHVH to regulate properly?
  The LT317AHVH requires a minimum load current of 3.5mA to regulate properly. If the load current is less than this, the output voltage may not be regulated accurately.
• Can I use the LT317AHVH as a high-current regulator?
  While the LT317AHVH can deliver up to 1.5A of output current, it's not recommended for high-current applications due to thermal limitations. For high-current applications, consider using a heat sink or a more suitable regulator.
• How do I protect the LT317AHVH from input voltage transients?
  To protect the LT317AHVH from input voltage transients, use a TVS diode or a transient voltage suppressor at the input. This will help absorb voltage spikes and prevent damage to the regulator.
