NX1117C25Z,115 datasheet by NXP Semiconductors

NX1117C25Z,115 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the NX1117C25Z,115 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 stability and prevent oscillations in the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, place the output capacitor close to the output pin and use a low-ESR capacitor.
• What is the minimum input capacitance required for the NX1117C25Z,115?
  The minimum input capacitance required is 1uF, but it's recommended to use a 10uF capacitor to ensure stability and reduce input voltage ripple.
• Can I use the NX1117C25Z,115 in a high-temperature environment?
  The NX1117C25Z,115 has a maximum operating temperature of 125°C. However, it's recommended to derate the output current and input voltage to prevent overheating and ensure reliable operation.
• How do I calculate the power dissipation and junction temperature of the NX1117C25Z,115?
  Use the formula: Pd = (Vin - Vout) x Iout. Then, calculate the junction temperature using the thermal resistance (Rthja) and the power dissipation: Tj = Ta + (Rthja x Pd), where Ta is the ambient temperature.
