Quality Control: Learn More
The STMicroelectronics LD39300PT-R is a positive adjustable linear voltage regulator IC designed for high-current applications. This device offers a robust solution for power management in demanding environments, delivering up to 3A of output current. Featuring a low quiescent current of 5 µA and a maximum input voltage of 6V, it is suitable for battery-powered systems and other efficiency-critical designs. The adjustable output voltage range, from a minimum of 1.22V to a maximum of 5V, provides flexibility in system design. Protection features include over-current and over-temperature shutdown, enhancing reliability. The regulator's low dropout voltage of 0.4V at 3A minimizes power dissipation. Its PPAK (TO-252-5, DPAK) surface-mount package is ideal for automated assembly processes. Applications span automotive, industrial, and consumer electronics sectors requiring stable and high-current voltage regulation. The device operates across a temperature range of -40°C to 125°C.
