L4975A Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L4975A can handle?
  The L4975A can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I choose the right output capacitor for the L4975A?
  Choose an output capacitor with a low ESR (Equivalent Series Resistance) and a capacitance value between 10uF to 100uF. A 22uF capacitor is a good starting point.
• What is the minimum input voltage required for the L4975A to operate?
  The L4975A can operate with input voltages as low as 7V, but the output voltage regulation may not be guaranteed below 8V.
• Can I use the L4975A in a high-temperature environment?
  The L4975A is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage to ensure reliable operation above 125°C.
• How do I calculate the output voltage of the L4975A?
  The output voltage of the L4975A is determined by the resistor divider network between the output and the ADJ pin. Use the formula: Vout = 2.5V x (1 + R1/R2) to calculate the output voltage.
