KA3525A Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the KA3525A is 7V to 25V, although it can operate up to 30V with reduced performance.
  • To ensure stable operation, ensure that the input voltage is well-regulated, decouple the input and output with suitable capacitors, and provide a stable reference voltage to the REF pin.
  • The maximum output current capability of the KA3525A is 1A, although this can be increased with the use of an external pass transistor.
  • The output voltage of the KA3525A can be adjusted by connecting a resistive divider network between the output and the ADJ pin, and adjusting the ratio of the resistors to set the desired output voltage.
  • The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is disabled and the output voltage is turned off.
