78SR115HC Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the 78SR115HC?
  The maximum input voltage that can be applied to the 78SR115HC is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the 78SR115HC is stable and doesn't oscillate?
  To ensure stability, use a minimum output capacitance of 10uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output capacitor.
• What is the minimum input voltage required for the 78SR115HC to function properly?
  The minimum input voltage required for the 78SR115HC to function properly is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the 78SR115HC in a high-temperature environment?
  The 78SR115HC 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 at high temperatures.
• How do I protect the 78SR115HC from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the 78SR115HC from input voltage transients.
