LD1117DT25TR ST LDO Regulator | DPAK | 2.5V Output, 800mA

Product Overview

The LD1117DT25TR from STMicroelectronics is a low dropout voltage regulator (LDO) capable of delivering up to 800 mA output current. It features a fixed output voltage of 2.5V with high accuracy. The device is housed in a DPAK (TO-252) surface-mount package, making it suitable for space-constrained applications. With a dropout voltage as low as 1.1V at full load, it ensures efficient regulation even with small input-output voltage differentials. The LD1117DT25TR includes internal current limiting and thermal shutdown protection, enhancing system reliability.
