BA4558RF-E2 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the BA4558RF-E2 is 4.5V to 18V.
  • To ensure the stability of the output voltage, it is recommended to use a capacitor with a value of 1uF or more between the output pin and the GND pin, and to keep the input voltage stable.
  • The maximum output current of the BA4558RF-E2 is 3A.
  • To protect the BA4558RF-E2 from overheating, it is recommended to provide a heat sink or a thermal pad, and to ensure good airflow around the device.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it is low, the regulator is disabled.
