L4995AKTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4995AKTR?
  The maximum input voltage that can be applied to the L4995AKTR is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L4995AKTR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the L4995AKTR to operate?
  The minimum input voltage required for the L4995AKTR to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the L4995AKTR in a high-temperature environment?
  The L4995AKTR is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation and prevent overheating.
• How do I calculate the output voltage of the L4995AKTR?
  The output voltage of the L4995AKTR is adjustable using the FB pin and an external resistor divider. The output voltage can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider.
