LT1117CST-3.3 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1117CST-3.3 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.

  • The LT1117CST-3.3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage to ensure reliable operation.

  • To ensure stability, it's recommended to use a minimum output capacitance of 10uF with an ESR of less than 5 ohms. Additionally, the input capacitance should be at least 1uF with an ESR of less than 5 ohms.

  • The LT1117CST-3.3 is not a low-dropout regulator (LDO), and it requires a minimum input-to-output voltage differential of 1.5V to maintain regulation. If you need an LDO, consider using a different part like the LT1963A-3.3.

  • The power dissipation of the LT1117CST-3.3 can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
