78SR108HC Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the 78SR108HC can handle?
  The 78SR108HC can handle an input voltage up to 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the 78SR108HC is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum of 10uF capacitor at the input and output, and keep the output capacitor value between 10uF to 100uF. Also, keep the input and output capacitors close to the regulator.
• What is the minimum load current required for the 78SR108HC to function properly?
  The 78SR108HC requires a minimum load current of 5mA to maintain regulation. If the load current is less than 5mA, the output voltage may not be regulated properly.
• Can I use the 78SR108HC in a high-temperature environment?
  The 78SR108HC 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 voltage at high temperatures to ensure reliable operation.
• How do I protect the 78SR108HC from input voltage transients?
  To protect the 78SR108HC from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input. This will help absorb voltage spikes and prevent damage to the regulator.
