Pinout

The AMS1084CM-3.3 is a low dropout voltage regulator with a fixed output voltage of 3.3V. It typically comes in a TO-263 or TO-220 package and has three pins. The pin configuration is as follows:
1. Pin 1 - Adjust/Ground (Adj/GND): In the fixed version like the 3.3V model, this pin is connected to ground. It is used as an adjustment pin in versions that allow output voltage adjustment.
2. Pin 2 - Output (Vout): This is the output pin where the regulated 3.3V voltage is provided. It should be connected to the load that requires the 3.3V supply.
3. Pin 3 - Input (Vin): This is the input pin where the unregulated input voltage is connected. The input voltage must be higher than the desired output voltage to ensure proper regulation.
The AMS1084CM-3.3 is designed for applications that require a stable 3.3V output with a low dropout voltage, making it suitable for powering microcontrollers, sensors, and other low-voltage electronic components.
