L4976D Frequently Asked Questions (FAQs)

  • The L4976D can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a minimum ESR of 0.1 ohms. Also, keep the input and output capacitors close to the IC and use a good quality PCB layout.
  • The L4976D can deliver up to 1.5A of output current, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
  • The output voltage of the L4976D can be adjusted by using a resistive divider network between the output and the ADJ pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage of 2.5V.
  • The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is pulled low, the regulator is disabled and the output voltage is turned off.
