BA4558 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the BA4558 is 4.5V to 18V, although it can operate up to 20V with reduced performance.
  • To ensure stability, make sure to decouple the power supply with a 10uF capacitor, use a low-ESR capacitor for the output filter, and keep the PCB layout clean and compact.
  • The maximum output current of the BA4558 is 1A, but it can be increased to 2A with an external transistor.
  • Yes, the BA4558 can operate up to 125°C, but the output current and voltage regulator performance may degrade at high temperatures.
  • The output voltage of the BA4558 can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network.
