The SP7625 is a low-voltage differential linear regulator with the following pin functions: the input voltage VIN is connected to the VIN pin, the output voltage VOUT is connected to the VOUT pin, and the ground GND of the power supply is connected to the GND pin.
The ADJ pin is used to adjust the output voltage by connecting a resistor. The EN pin is the enable pin that controls the switch, the high level enable switch, and the low level off switch.
The FB pin is a feedback pin that keeps the output voltage stable and can be set by connecting a resistor. In short, the function of the SP7625 pin is very clear, which can achieve stable voltage output.
5-pin step-down chip pin functions: 1 pin power control pressure, 2 pin output pressure, 3 pin input pressure, 4 pin output pressure, 5 pin input end pressure.
