The SI-8005Q is a buck switching regulator IC with a built-in power MOS.
Due to a current control system, it is applicable to such a super low ESR capacitor as a ceramic capacitor.
It is provided with various protection functions such as overcurrent protection, low input prohibition, overheat protection etc.
In order to protect the IC against in-rush current at start-up, the soft start function is provided.
The soft start time can be set by connecting external capacitors.
A function to turn on/off external signals is also provided and by sending external signal to the EN terminal, the SI-8105Q can be turned on/off.
This device is supplied in the small and thin type HSOP 8-pin package including a heat slug on the backside.
The SI-8105QL ismounted in the DIP 8-pin package for flow mounting /power supply board (single side surface board).
