  • If you ripple to lower the need, please install LC filter at the output

  • Dynamic response speed: 5% 200uS

  • Short circuit protection: current limit (3A), self-recovery

  • Over-temperature protection: 150 ° c

  • Static current: 7-20 mA (the higher the input voltage, the higher of the static current)

  • Input reverse polarity protection: None

  • Wiring: Welding, the SIP-3 package, compatible with the LM7805.


  • Integrated within the filter capacitor, even without to external capacitor, the item can work properly.

  • In order to lower the output ripple, please install filter capacitor at the input and output port.
