78SR105TC Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the 78SR105TC can handle?
  The 78SR105TC can handle an input voltage up to 35V, but it's recommended to keep it below 30V for reliable operation and to prevent overheating.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable output voltage, make sure to use a suitable input capacitor (e.g., 10uF) and output capacitor (e.g., 10uF to 22uF) with low ESR, and keep the input voltage above the minimum required voltage (7.5V for 5V output).
• What is the minimum input voltage required for the 78SR105TC to operate?
  The minimum input voltage required for the 78SR105TC to operate depends on the output voltage. For a 5V output, the minimum input voltage is 7.5V, while for a 12V output, it's 14.5V.
• Can I use the 78SR105TC in a high-temperature environment?
  The 78SR105TC has a maximum operating temperature of 125°C. While it can operate in high-temperature environments, it's essential to ensure proper heat sinking and thermal management to prevent overheating and reduce the risk of failure.
• How do I calculate the power dissipation of the 78SR105TC?
  To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. Make sure to consider the maximum power dissipation rating (15W) and thermal resistance (25°C/W) when designing your application.
