LM117HVGWRQMLV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM117HVGWRQMLV?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• Can I use the LM117HVGWRQMLV in a high-temperature environment?
  The LM117HVGWRQMLV is rated for operation up to 125°C, but the output voltage and current may degrade at high temperatures. It's essential to consider the thermal design and heat sinking to ensure reliable operation.
• How do I ensure the stability of the output voltage with the LM117HVGWRQMLV?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, keep the input capacitance as close to the regulator as possible and use a low-ESR capacitor.
• What is the minimum input voltage required for the LM117HVGWRQMLV to operate?
  The minimum input voltage required is 3.5V, but it's recommended to keep it above 4V for optimal performance and to ensure the output voltage remains within the specified tolerance.
• Can I use the LM117HVGWRQMLV in a switching regulator application?
  No, the LM117HVGWRQMLV is a linear voltage regulator and not suitable for switching regulator applications. It's designed to provide a stable output voltage with low noise and high PSRR (Power Supply Rejection Ratio).
