Pinout

The NCP303LSN47T1G is a low-dropout (LDO) voltage regulator with a pin count of 5. The functions of its pins are as follows:
1. Input (VIN): This pin is where the input voltage is applied. It should be greater than the output voltage but within the specified range.
2. Ground (GND): This pin is connected to the ground of the circuit.
3. Output (VOUT): This pin provides the regulated output voltage, which is 4.7V in the case of the NCP303L variant.
4. Control (EN): This is the enable pin. When pulled high, it enables the regulator; when low, it disables the output.
5. Bypass (BP): This pin is used for bypassing and improving transient response; it is typically connected to an external capacitor.
This device is designed for applications requiring a stable output voltage with low quiescent current.
