Pinout

The ADP3335ARMZ-3.3 is a low-dropout (LDO) voltage regulator from Analog Devices, featuring a 5-pin package. The pinout and their functions are as follows:
1. Input (VIN): This pin is used to connect the input voltage supply, which should be higher than the desired output voltage.
2. Ground (GND): The ground reference for the device, connected to the circuit ground.
3. Output (VOUT): This pin provides the regulated output voltage (3.3V in this case).
4. Adjust (ADJ): This pin is used for adjusting the output voltage, allowing for different output levels if required (typically used in versions with adjustable output).
5. Enable (EN): This pin is used to enable or disable the regulator. When high, the device is active; when low, it is in a low-power shutdown state.
The ADP3335ARMZ-3.3 is known for its low noise and high power supply rejection ratio, making it suitable for sensitive applications.
