REG1117-2.85 TI LDO Regulator | SOT-223-4 | 2.85V Fixed Output, 800mA

Product Overview

The REG1117-2.85 from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering a fixed output voltage of 2.85V with an output current capability of up to 800mA. Housed in a compact SOT-223-4 package, this device is designed for space-constrained applications requiring a stable and accurate power supply. The REG1117-2.85 features a low dropout voltage of typically 1.1V at full load, making it suitable for battery-powered systems and post-regulation scenarios. With built-in current limiting and thermal shutdown protection, it ensures reliable operation under fault conditions.
