LT3504EUFD#TRPBF Frequently Asked Questions (FAQ)

  • A good PCB layout for the LT3504EUFD#TRPBF involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.

  • To ensure stability, use a minimum output capacitance of 10uF, keep the output capacitor's ESR below 1 ohm, and avoid using capacitors with high ESR or ESL. Also, ensure the input capacitor is at least 10uF and has a low ESR.

  • The maximum input voltage that can be applied to the LT3504EUFD#TRPBF is 15V, but it's recommended to keep the input voltage below 12V for optimal performance and reliability.

  • The output voltage of the LT3504EUFD#TRPBF can be calculated using the formula: Vout = (R1/R2) * (1.22V), where R1 and R2 are the resistors in the feedback network.

  • The thermal shutdown temperature of the LT3504EUFD#TRPBF is typically around 150°C, but it can vary depending on the specific application and operating conditions.
