LM317T STMicroelectronics Adjustable Linear Voltage Regulator (TO-220-3)

The fixed 5V LM7805 already in the catalog covers the single most common regulation need, but plenty of projects need a specific voltage that isn't exactly 5V, and that's where an adjustable regulator like the LM317 earns its place. This genuine STMicroelectronics LM317T sets its output anywhere from 1.25V up to 37V through a simple two-resistor divider, delivering up to 2.2A in the sturdy TO-220 package, giving a builder one part that covers a wide range of custom voltage needs instead of stocking a fixed regulator for every value.
