Pinout
1. Pin 1 (ADJ/GND): This is the Adjust or Ground pin. For fixed output versions like the NCP1117LPST33T3G, this pin is typically connected to ground. In adjustable versions, it is used to set the output voltage via an external resistor divider.
2. Pin 2 (VOUT): This is the output pin, which provides the regulated voltage. For the NCP1117LPST33T3G, the output voltage is fixed at 3.3V.
3. Pin 3 (VIN): This is the input pin, where the input voltage is applied. The input voltage must be higher than the desired output voltage to maintain regulation.
The NCP1117LPST33T3G is often used in applications requiring a stable 3.3V supply, with features like low dropout voltage and current limit protection.
