The IP5407 is a low-voltage differential linear regulator with the following pin description:
1. Input power pin (VIN) : Used to access the input power supply, the input voltage range is 2.5V to 6.0V.
2. Ground pin (GND) : used to connect the ground cable.
3. Output voltage pin (VOUT) : used to output stable voltage, output voltage is 1.8V.
4. System RESET pin: Used to start or reset the system.
5. Power management pin (ENABLE) : used to control the regulator switch, when the pin input high power level, the regulator is in the enabled state, the output voltage is normal; When the pin input level is low, the regulator is turned off and the output voltage is 0V.
It should be noted that the pin instructions of the IP5407 may vary from manufacturer to manufacturer or from model to model, so it is necessary to operate according to the specific product manual when using.
