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.
A 5-pin power supply chip is an integrated circuit that converts the input voltage to a stable output voltage and provides overload protection and short circuit protection. Often used in electronic devices, such as mobile phones, laptops, digital cameras, etc. The common 5-pin power supply chips are LM7805, LM2940, LM2937, etc., which have different input voltage ranges, output voltage, maximum output current and other characteristics. Choosing the appropriate 5-pin power supply chip can ensure the stability and safety of the circuit.
