LT3991IMSE#TRPBF datasheet by Linear Technology

LT3991IMSE#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3991 can handle?
  The LT3991 can handle input voltages up to 60V, but it's recommended to keep the input voltage below 50V for optimal performance and reliability.
• 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, keep the output voltage within the recommended range of 0.8V to 15V.
• What is the maximum output current that the LT3991 can deliver?
  The LT3991 can deliver up to 1.5A of output current, but it's recommended to keep the output current below 1.2A for optimal performance and reliability.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive divider network between the output pin and the ground 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.
