Package
The NCP1117DT33T5G is a low dropout voltage regulator in a DPAK (TO-252) surface mount package.
Pinout
The NCP1117DT33T5G is a low dropout voltage regulator with a fixed output voltage of 3.3V. It is part of the NCP1117 series by ON Semiconductor. The device comes in a DPAK-3 (TO-252) package, which features three pins. Here is a brief overview of its pin functions:
1. Pin 1 (ADJ/GND): This is the ground pin. For the adjustable version of the NCP1117 series, this pin serves as the adjust pin, but for the fixed version like the NCP1117DT33T5G, it is simply connected to ground.
2. Pin 2 (VOUT): This is the output pin that provides a regulated 3.3V output voltage. It should be connected to the load that requires regulation.
3. Pin 3 (VIN): This is the input pin where the unregulated voltage is applied. It needs to be higher than the desired output voltage to maintain proper regulation.
The NCP1117DT33T5G is widely used in applications requiring a stable 3.3V supply, offering features like thermal protection and current limiting.
