NX1117C15Z,115 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the NX1117C15Z?
  The maximum input voltage is 20V, but it's recommended to keep it below 18V for reliable operation and to prevent overheating.
• How do I ensure stability and prevent oscillations in the NX1117C15Z?
  To ensure stability, use a minimum output capacitance of 10uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, keep the input and output capacitors close to the regulator and use a low-ESR capacitor for the output.
• What is the thermal shutdown temperature of the NX1117C15Z?
  The thermal shutdown temperature is typically around 150°C to 160°C, but this can vary depending on the specific device and operating conditions.
• Can I use the NX1117C15Z in a high-temperature environment?
  While the NX1117C15Z can operate up to 125°C, it's not recommended for high-temperature applications. For temperatures above 85°C, consider using a heat sink or a more suitable regulator designed for high-temperature operation.
• How do I calculate the power dissipation of the NX1117C15Z?
  Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Make sure to consider the maximum junction temperature (TJ) and thermal resistance (RθJA) when calculating the power dissipation.
