LM338T is a three-terminal adjustable positive linear voltage regulator that can deliver up to 5A of output current. It features a wide input voltage range of 4.2V to 30V, making it suitable for a variety of applications. The output voltage can be adjusted from 1.2V to 30V using an external resistor network, making it highly versatile. LM338T has built-in thermal overload protection and current limiting to ensure safe operation under all conditions. It also has a low dropout voltage, which means it can regulate output voltage with a small voltage difference between the input and output. This makes it efficient and minimizes power dissipation. The device comes in a TO-220 package, making it easy to mount on a heatsink for enhanced thermal performance. LM338T is a reliable and robust voltage regulator that is widely used in power supply and battery charger applications
