LD2981ABM33TR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the IC to minimize noise and oscillations.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for optimal performance and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.24V), and R1 and R2 are the resistors in the feedback network.
  • The EN pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled and the output voltage is turned off.
