LM317
The LM317 is a popular adjustable voltage regulator used to provide a stable output voltage from a varying input voltage source. It is a three-terminal device capable of supplying a maximum of 1.5A of current. The output voltage can be adjusted using external resistors, making it versatile for various applications requiring a fixed or variable voltage supply.
