LT1117CST-5#PBF datasheet by Linear Technology

LT1117CST-5#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1117CST-5#PBF can handle?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.05 ohms or less, and a minimum input capacitance of 1uF with an ESR of 0.1 ohms or less.
• What is the dropout voltage of the LT1117CST-5#PBF?
  The dropout voltage is typically around 1.2V, which means the input voltage should be at least 1.2V higher than the output voltage for proper regulation.
• How do I calculate the power dissipation of the LT1117CST-5#PBF?
  Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT, where VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current.
• Is the LT1117CST-5#PBF short-circuit protected?
  Yes, the LT1117CST-5#PBF has built-in short-circuit protection, which limits the output current to prevent damage in case of a short circuit.
