Package
The LM2825N-5.0 is a voltage regulator from Texas Instruments, and it is typically housed in a 7-pin TO-220 package. This package type is designed for through-hole mounting, offering efficient heat dissipation suitable for power applications.
Pinout
The LM2825N-5.0 is a step-down voltage regulator integrated circuit designed to provide a fixed 5.0V output from a higher voltage input. It features a 5-pin configuration. The pin functions are as follows:
1. Pin 1 (VIN): This is the input voltage pin where the input voltage is applied. It is capable of operating with input voltages higher than the output voltage.
2. Pin 2 (GND): The ground pin is used for the return path of the input and output currents. It acts as a reference point for the circuit.
3. Pin 3 (SW): The switch pin is internally connected to the power switch and is used for the switching operation of the internal circuitry to regulate the output voltage.
4. Pin 4 (VOUT): This is the output voltage pin where the regulated 5.0V is provided.
5. Pin 5 (FB): The feedback pin is used to sense the output voltage and is connected internally to the regulation control loop to maintain the stable output voltage.
These pins facilitate the functioning of the LM2825N-5.0 as a reliable and efficient voltage regulator.
