L4995RJ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4995RJ?
  The maximum input voltage that can be applied to the L4995RJ is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L4995RJ 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 (at least 10uF), and add a 1nF capacitor between the VIN and EN pins.
• What is the minimum input voltage required for the L4995RJ to operate?
  The minimum input voltage required for the L4995RJ to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
• Can I use the L4995RJ in a high-temperature environment?
  The L4995RJ is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the L4995RJ?
  The output voltage of the L4995RJ can be calculated using the formula: VOUT = (R1 / R2) * 1.25V, where R1 and R2 are the resistors connected to the FB pin.
