L6986HTR datasheet by STMicroelectronics

L6986HTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L6986HTR?
  The maximum input voltage that can be applied to the L6986HTR is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L6986HTR operates within its thermal limits?
  To ensure the L6986HTR operates within its thermal limits, make sure to provide adequate heat sinking, keep the ambient temperature below 85°C, and avoid high power dissipation during operation.
• What is the minimum input capacitance required for stable operation?
  The minimum input capacitance required for stable operation is 10uF, but it's recommended to use a higher value (e.g., 22uF) to ensure stable operation over the entire input voltage range.
• Can I use the L6986HTR in a high-temperature environment?
  The L6986HTR is rated for operation up to 150°C, but it's recommended to derate the output current and power dissipation at high temperatures to ensure reliable operation.
• How do I adjust the output voltage of the L6986HTR?
  The output voltage of the L6986HTR can be adjusted by changing the value of the feedback resistors (R1 and R2) according to the formula provided in the datasheet.
