Pinout
1. Pin 1 (IN): This is the input pin for the regulator. It is where the unregulated voltage is supplied.
2. Pin 2 (GND): The ground pin. It is the common ground for the input and output voltages.
3. Pin 3 (EN): Enable pin. This pin is used to enable or disable the regulator. Bringing this pin high enables the regulator, while low disables it.
4. Pin 4 (NR/FB): Noise Reduction/Feedback pin. For fixed output voltage versions, a capacitor can be connected to this pin for noise reduction. For adjustable versions, this pin can be used to set the output voltage.
5. Pin 5 (OUT): This is the output pin where the regulated voltage is delivered.
This LDO is known for its low noise and low dropout performance, making it suitable for sensitive analog applications.
