L6986H3V3 datasheet by STMicroelectronics

L6986H3V3 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L6986H3V3?
  The maximum input voltage that can be applied to the L6986H3V3 is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the L6986H3V3 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the layout guidelines in the datasheet, use a sufficient output capacitor (at least 10uF), and add a 10nF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the L6986H3V3 to operate?
  The minimum input voltage required for the L6986H3V3 to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L6986H3V3 in a high-temperature environment?
  The L6986H3V3 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 L6986H3V3?
  The output voltage of the L6986H3V3 is fixed at 3.3V, but it can be adjusted by using an external resistor divider network between the VOUT and GND pins.
