Pinout
The LM2825N-5.0 is a voltage regulator integrated circuit designed to provide a fixed 5.0V output. It comes in a standard 5-pin package. Here are the pin functions:
1. Pin 1 (Enable/Shutdown): This pin is used to enable or disable the regulator output. A high voltage level enables the regulator, while a low voltage level shuts it down.
2. Pin 2 (Input): This is the input pin where the unregulated input voltage is applied. It accepts a DC voltage typically higher than the desired output voltage.
3. Pin 3 (Ground): This is the ground pin and serves as the common reference point for the input and output voltages.
4. Pin 4 (Output): This pin provides the regulated 5.0V output. It is connected to the load that requires a stable voltage supply.
5. Pin 5 (Feedback/Adjust): In some configurations, this pin can be used to adjust the output voltage or is internally connected to provide a fixed output. However, in the LM2825N-5.0 version, it is typically used for feedback to maintain the fixed 5.0V output.
This IC is ideal for applications requiring a stable 5.0V power supply with features such as thermal shutdown and current limiting.
