Pinout
The NCP1117DT12G is a low dropout (LDO) voltage regulator from ON Semiconductor. It typically comes in a 3-pin DPAK package. Here's a breakdown of its pin count and functions:
1. Pin 1 (Adjust/ Ground): This pin is used for either ground (in fixed output versions) or as an adjust pin (in adjustable versions). In the NCP1117DT12G, which is a fixed 1.2V output version, this pin serves as the ground.
2. Pin 2 (Output): This pin is the regulated output voltage, providing a fixed 1.2V in this specific model.
3. Pin 3 (Input): This pin is the input supply voltage. It should be higher than the desired output voltage by at least the dropout voltage to ensure proper regulation.
The package also includes a tab connected to the ground (Pin 1) for heat dissipation purposes. This regulator is suitable for applications requiring a 1.2V fixed output with low dropout performance.
