What is the LM317 and its Pinout?
The LM317 is a versatile and popular integrated circuit (IC) that functions as a positive adjustable voltage regulator. It's renowned for its simplicity, cost-effectiveness, and ability to provide a stable output voltage that can be adjusted over a wide range. The "LM317 Распиновка Datasheet" is essentially the technical documentation that details the function and electrical characteristics of each pin on the LM317 package. This datasheet is your primary reference for correctly connecting the IC into your circuit.
The typical LM317 package has three pins, and their functions are clearly defined in the Lm317 Распиновка Datasheet. These pins are:
- Input (Vin): This is where the unregulated DC voltage is applied.
- Output (Vout): This pin provides the regulated, stable output voltage.
- Adjust (Adj): This is the control pin that allows you to set the output voltage.
The Lm317 Распиновка Datasheet will also specify the typical voltage ranges and current capabilities. For example, a common setup involves connecting a resistor between the Adjust pin and ground, and another resistor between the Output pin and the Adjust pin. The ratio of these resistors determines the output voltage. The datasheet provides the formulas and typical values to help you calculate the correct resistor values for your desired output voltage. Understanding these connections is paramount for building functional and safe circuits .
Here's a simplified representation of how the pins are typically used in a voltage regulator circuit:
| Pin | Function | Typical Connection |
|---|---|---|
| Input (Vin) | Unregulated DC Voltage In | Connected to the positive terminal of the power source. |
| Output (Vout) | Regulated DC Voltage Out | Connected to the load requiring the regulated voltage. |
| Adjust (Adj) | Voltage Setting | Connected via resistors to set the output voltage. |
