LT1172CQ#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT1172CQ is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed close to the output pin to minimize inductance.
  • The maximum output current that the LT1172CQ can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • To reduce noise and ripple, it's recommended to use a low-ESR output capacitor, and to add a 10uF ceramic capacitor in parallel with the output capacitor. Additionally, using a shielded inductor and keeping the layout compact can also help reduce noise and ripple.
  • The thermal shutdown temperature of the LT1172CQ is 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
