Pinout
Here is a brief description of the pin functions:
1. VOUT: Output voltage pin, provides the regulated 3.3V.
2. GND: Ground connection.
3. VIN: Input voltage pin, requires a voltage higher than 3.9V to function correctly.
4. ADJ/FB (Feedback): Used for output voltage adjustment in versions where output voltage is not fixed.
5. SHDN (Shutdown): When this pin is low, the regulator is disabled; if high or not connected, the regulator is enabled.
6. COMP (Compensation): Used for frequency compensation and noise filtering.
7. ERROR: Error flag output that signals if the output voltage is incorrect.
8. NC (No Connect): Not connected internally, typically used to aid in routing the circuit board.
Always refer to the manufacturer's datasheet for the most accurate and detailed information.
