LT1171CT Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1171CT is 15V, but it's recommended to keep it below 12V for reliable operation.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the regulator to minimize parasitic inductance.

  • The LT1171CT is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and input voltage according to the datasheet's thermal derating curves.

  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Iq is the quiescent current. Make sure to consider the thermal resistance of the package and the PCB when calculating the junction temperature.

  • No, the LT1171CT is a linear voltage regulator and is not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
