1 Five-pin power chip pins have multiple functions
2 The first pin is the input power supply, the second pin is the ground, the third pin is the output power supply, the fourth pin is the power adjustment pin, and the fifth pin is the overload protection pin.
Where, the fourth pin can adjust the output voltage through the external capacitance, and the fifth pin can set the overload protection current through the external resistance. In addition, the use of five-pin power supply chip can improve the stability and safety of the circuit, and is widely used in various electronic devices.
