Pinout
1. Pin 1 (Adjust/Ground): This pin functions as either the ground connection or the adjustment pin depending on whether the device is a fixed or adjustable version. For the LM1117IMP-5.0, which is a fixed output version, this pin is connected to ground.
2. Pin 2 (Output): This pin provides the regulated output voltage of 5.0V. It is where the load is connected to receive the stable voltage supply.
3. Pin 3 (Input): This pin is connected to the input voltage source. It should be higher than 5.0V (typically at least 6.2V) to ensure proper regulation.
The LM1117 series is known for low dropout voltage, which makes it suitable for applications requiring a stable 5.0V output with a relatively low input voltage difference.
