Package
Pinout
1. Input (Vin) - This pin (Pin 1) is where the input voltage is applied. The input voltage should be higher than the desired output voltage by at least 3V for proper regulation.
2. Output (Vout) - This pin (Pin 2) provides the regulated output voltage. The output can be adjusted between 1.25V and 37V using external resistors.
3. Adjust (Adj) - This pin (Pin 3) is used to set the output voltage. By connecting a resistor network between the output and this pin, the output voltage can be adjusted according to the desired value.
The LM317 is widely used in power supply applications due to its versatility and ability to provide stable output voltage.
