Pinout
1. Pin 1 (ADJ/GND): This is the adjust pin for the adjustable version or ground pin for the fixed voltage version. In fixed output configurations like the LD1085D2T33R, which outputs 3.3V, it serves as the ground pin.
2. Pin 2 (VOUT): This is the output pin where the regulated voltage is provided. The LD1085D2T33R provides a fixed output voltage of 3.3V.
3. Pin 3 (VIN): This is the input pin where the unregulated input voltage is supplied, which should be higher than the desired output voltage to ensure proper regulation.
Additionally, the package has a tab that is typically connected to ground, aiding in heat dissipation. The LD1085 series is known for a dropout voltage of approximately 1.2V at full load, making it suitable for applications requiring a low dropout voltage regulator with high current capability.
