L4984DTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4984DTR?
  The maximum input voltage that can be applied to the L4984DTR is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the L4984DTR operates within its thermal limits?
  To ensure the L4984DTR operates within its thermal limits, make sure to provide adequate heat sinking, keep the device away from heat sources, and avoid high ambient temperatures.
• What is the minimum input voltage required for the L4984DTR to operate?
  The minimum input voltage required for the L4984DTR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L4984DTR in a high-temperature environment?
  The L4984DTR is rated for operation up to 150°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and ensure proper heat sinking in high-temperature environments.
• How do I calculate the output voltage of the L4984DTR?
  The output voltage of the L4984DTR can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage (typically 2.5V).
