L6986FTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L6986FTR can handle?
  The L6986FTR can handle a maximum input voltage of 38V, but it's recommended to keep it below 36V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (1.2V to 15V). Also, ensure that the input voltage is within the recommended range and the input capacitor is properly sized.
• What is the maximum output current that the L6986FTR can deliver?
  The L6986FTR can deliver a maximum output current of 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I reduce the noise and ripple on the output voltage?
  To reduce noise and ripple, use a low-ESR output capacitor, keep the output voltage within the specified range, and ensure that the input voltage is stable and within the recommended range. You can also add a noise-reducing capacitor (e.g., 10nF) between the output and ground.
• What is the purpose of the EN (enable) pin, and how do I use it?
  The EN pin is used to enable or disable the regulator. When EN is high (logic level), the regulator is enabled, and when EN is low (logic level), the regulator is disabled. You can use the EN pin to turn the regulator on and off, or to implement a power-saving mode.
