LT3991EMSE-3.3#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3991EMSE-3.3#PBF is 15V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled with a 10uF capacitor.
  • The maximum output current that the LT3991EMSE-3.3#PBF can deliver is 1.5A. Exceeding this current may cause the device to overheat or shut down.
  • To reduce the noise and ripple in the output voltage, it is recommended to use a low-ESR output capacitor and to add a noise-reducing capacitor (e.g. 10nF) between the output and ground.
  • The thermal shutdown temperature of the LT3991EMSE-3.3#PBF is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
