LT3990IMSE#PBF datasheet by Linear Technology

LT3990IMSE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3990 can handle?
  The LT3990 can handle input voltages up to 60V, but it's recommended to operate within the 5.5V to 40V range for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the input capacitor.
• What is the maximum output current that the LT3990 can provide?
  The LT3990 can provide up to 2A of output current, but it's recommended to operate within the 1.5A range for optimal performance and thermal considerations.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage.
• What is the purpose of the EN pin?
  The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
